Definitions

  • the invention relates to a method for determining a mass for the soil stiffness (degree of compaction) of a compacted or compacted soil area according to the preamble of patent claim 1, as well as a soil compacting device according to the preamble of patent claim 7.
  • a compression should always be optimal, d. H. fastest and with the least expenditure of energy feasible when resonance of the soil compaction system occurred.
  • the soil compacting system was formed of the soil to be compacted and the compacting device acting on it.
  • the accelerometer measures a non-harmonic vibration.
  • the excitation was increased or a stiffer and more elastic ground was reached, a periodicity of the oscillation occurred at half the frequency. This condition was considered stable. If the stimulation was increased even more, or if the ground was even stiffer, jumping of the bandage occurred. The measured quotient was significantly higher than mentioned above.
  • the object of the invention is to compress a soil area to a predetermined or to a maximum of a machine design according to achievable soil stiffness, to determine the degree of compaction achieved and to provide a soil compaction device with which this optimal soil compaction is to make.
  • a soil compaction with a predetermined or maximum possible soil stiffness is a ground contact unit acting on the floor area of a soil compacting device moves over the latter. In this case acts on the ground contact unit a time periodically changing with at least one action frequency force.
  • the vibrations of a vibration system consisting of the soil compacting device with the ground contact unit and the respective ground area, are determined.
  • the vibration form of the vibration of the vibration system is recorded, and the soil rigidity (degree of compaction) is then determined from the vibration mode, from the engine parameters of the soil compacting device and from the timing of the soil compaction force.
  • the subharmonics are determined, but also their amplitudes, which are set in relation to the amplitude of the action frequency.
  • the maximum amplitude values will be used for this purpose.
  • a sensor will be mounted on the ground contact unit next to a sensor for the subharmonics, which measures the temporal deflection in the direction of soil compaction.
  • the temporal deflection of the excitation can also be measured; However, it can easily be determined from the instantaneous position of the imbalance or imbalances.
  • the temporal position of the maximum amplitudes (excitation oscillation to the vibration of the ground contact unit) will be determined with a comparator unit.
  • the excitation is preferably adjusted such that the maximum amplitude of the excitation by 90 ° to 180 °, preferably by 95 ° to 130 ° ahead of the maximum amplitude of the ground contact unit.
  • An adjustment of the exciting force may be avoided when using e.g. be achieved by two imbalances, which rotate at the same rotational speed and the angular distance is changeable.
  • the imbalances can be moved in the same direction or in opposite directions.
  • FIG. 1 For this purpose, a compactor 1 with rear, rubber-tired wheels 3 and a front bandage 5 as a ground contact unit and a chassis 6 is shown. Based on this system, a one-sided bond between a bottom region 7 to be compacted (substructure) and the compactor 1 (compacting device) is the main reason for the occurrence of nonlinear effects. The one-sided binding is justified by the fact that between the compactor 1 and the bottom portion 7 compressive forces but no tensile forces can be transmitted.
  • the compaction apparatus 1 When the maximum ground force values are exceeded, the compaction apparatus 1 periodically loses contact with the ground area 7 (subsurface). Additional non-linear elements of the soil properties, such as shear strain-controlled stiffness changes, can be neglected in comparison. Also, the superlinear spring characteristic of (rubber) damping elements 8 between the chassis 6 and ground contact unit 5 (bandage), or a superstructure 9 and an undercarriage 11 of a trench roller 12 explained later is of minor importance and does not significantly affect the calculation results of an analytical description. The same applies to a vibration plate 14 with a superstructure 15 and a lower carriage 17th
  • a compacting device generally, as well as the compactor 1 in FIG. 1 , a ground contact unit (bandage 5, undercarriage 11 or 17 ) with a vibrating part, for example with a rotating imbalance 13 with a mass m d including an imbalance exciter.
  • a static Auflastabout of the chassis 6 is based with a mass m f (static weight) via damping elements 8 (stiffness k G , damping c G ) from.
  • the static weight m f together with the damping elements 8 , produces a point-point-excited vibration system which is tuned low (low natural frequency).
  • the uppercarriage 9 or 15 or the chassis 6 acts in vibration mode with respect to the vibrations of the undercarriage 11 or 17 or the bandage 5 as a low-pass second order.
  • the vibration energy transmitted into the chassis 6 or the superstructure 9 or 15 is minimized.
  • the compacted or compacted bottom of the bottom region 7 is a building material for which, depending on the properties investigated, different models exist.
  • simple spring-damper models (stiffness k B , damping c B ) are used.
  • the spring properties take into account the contact zone between the soil compaction unit (bandage) and the elastic half-space (floor area).
  • the ground stiffness k B is a static, frequency-independent variable. This property could be demonstrated in the present application in the field trial for homogeneous and layered soils.
  • Equation (1) describes the associated motion differential equations for the degrees of freedom x d of the drum 5 and x f of the chassis 6 .
  • a soil reaction force F B between the bandage 5 and the compacted or compacted bottom region 7 controls the nonlinearity of the unilateral bond.
  • Vibratory plates ( FIG. 8 ) and rammers are basically the same considerations, taking into account the respective excitation principle result in analogous equations.
  • a numerical simulation allows the calculation of the solutions of equations (1).
  • the use of numerical solution algorithms is essential.
  • analytical calculation methods such as the averaging method, very good approximate solutions and statements of a fundamental nature can be made for a bifurcation of the fundamental vibrations for linear and nonlinear oscillations.
  • the averaging theory is described in Heatgg Roland (1998), “Nonlinear Vibrations in Dynamic Soil Compactors, Progress VDI, Series 4, VDI Verlag Dusseldorf.” This allows a good overall view about the occurring solutions.
  • analytical methods are associated with a disproportionately high outlay.
  • the coordinate system of equations (1) and (3) includes a static depression due to the dead weight (static load weight m f , swinging mass m d ).
  • the static sinking has to be subtracted for comparison purposes in the simulation result.
  • the initial conditions for the simulation are all set to "0". The results are given for the case of the steady state.
  • a solvent solver is chosen "ode 45" (Dormand-Price) with a variable integration step size (maximum step size 0.1 s) in the time range from 0 s to 270 s.
  • FIG. 3 is a comparison between a simulated and a measured case of a "strong jumping" of a compactor 1, here a compactor from Ammann AC 110 with 11 t total weight, shown.
  • a very good agreement between measured and calculated vibration behavior of a bandage 5 can be seen.
  • the measured data were recorded with an acceleration sensor mounted in the vertical direction on the non-rotating, oscillating part of the drum 5, the signal then amplified and analyzed using a program package, eg LabView / DIAdem®.
  • an amplitude A 0 of 1 mm and a ground stiffness k B of 140 MN / m have been specified. If one measures the movement in a time range for the "jumping" of a compactor, an iterative calculation method can be used to determine the actual soil stiffness down to a tolerance. For this purpose, the machine parameters of the compacting device, the operating state and the time position of the imbalance or imbalances must be known.
  • the practically measured and numerically simulated operating state of jumping of the pulley AC 110 with respect to the chaos theory represents a nonlinear system after the occurrence of the first period doubling.
  • the compactors are thus among the technical systems that are fundamentally capable of chaotic behavior. Their dynamics can thus be described using the methods of nonlinear and chaotic vibrational theory. This opens up a large field of different analysis methods, which can be applied in theory and practice of compaction technology.
  • F B is the force acting on the floor area; please refer FIG. 2 .
  • phase space representation with x 1 ( t ) - x 2 ( t ), or x ( t ) - ⁇ ( t ) is derived.
  • phase curves also referred to as orbitals
  • orbitals are closed circles or ellipses in the case of linear, stationary and monofrequent oscillations.
  • additional harmonics occur (periodic lifting of the bandage from the ground)
  • the harmonics can be recognized as modulated periodicities. Only at period doublings, ie subharmonic oscillations such as "jumping", does the original circle mutate into closed curves that have intersections in the phase space representation.
  • FIG. 5 illustrated phase curve.
  • the left display shows the measured and the left display the calculated values. Again the agreement of the simulation with the data measured in practice is shown.
  • FIG. 6 shows the measured, unmediated occurrence of jumping a roller (Ammann AC 110) during the transition of the machine from a very soft pad (tire) on an already compacted, hard sand-gravel mixture. With otherwise constant machine parameters, ground stiffness and damping are the variable system parameters.
  • the performed FFT shows in FIG. 6 left, the linear, monofrequency vibration behavior on the tire, Pneu (soft bottom) 204; the subharmonic oscillation, which additionally occurs on a hard surface, has about twice the amplitude compared to the fundamental mode (right illustration in FIG. 6 If you measure with each unbalance rotation in an excellent position of the rotating eccentric the corresponding vibration amplitude, or the deformation value of the movement, this is always constant on the tire (harmonious), on the hard pad, however, the value alternates according to the additional subharmonic vibration component. Due to their periodicity, harmonics can not be detected in this type of signal acquisition.
  • the measurement acquisition can in practice be triggered by the pulse of a Hall probe, which detects the zero crossing of the vibro wave.
  • the branches produce a cascade of new vibrational components with each half the frequency of the previous lowest frequency of the spectrum. Since the first branching off from the fundamental oscillation with the frequency f, or period T, splits off, the frequency cascade f, f / 2, f / 4, f / 8 etc. is generated. Analogously to the fundamental oscillation, the subharmonic harmonics also generate it creates a frequency continuum in the low-frequency range of the signal spectrum. This is also a specific property of the chaotic system, in this case the vibrating roller.
  • the system of the compactor is in a deterministic rather than a stochastic chaotic state. Since the parameters that cause the chaotic state are not all measurable (not fully observable), the operating state of the subharmonic vibrations can not be predicted for practical compaction.
  • the operating behavior in practice is also characterized by many imponderables, the machine can slip away due to the strong contact loss to the ground, the load of the machine by the low-frequency vibrations is very high. Ongoing further bifurcations of the machine behavior (unexpected) can occur, which immediately result in heavy additional loads. High stresses also occur between the bandage and the floor; This leads to the undesirable loosening of near-surface layers and causes grain breakup.
  • the subharmonic vibrations each represent a new state of motion of the machine
  • relative measurements eg. B. for detecting the compaction state of the soil
  • subharmonic oscillation on the reference inspection procedures such as the pressure plate test (DIN 18 196) be calibrated.
  • the correlation basically changes with the occurrence of the jumping; only within the respective branching state of the movement exists a linear relationship of the measured value with the soil stiffness.
  • the bifurcation occurs in the form of the period doubling scenario, the FIG. 7 or the FIG. 8 show this on the basis of the FFT spectrum for a trench roller or a vibrating plate.
  • phase space of the motions of the upper and lower carriage of the vibrating plate and the trench roller show in comparison to the corresponding orbital of the compactor ( FIG. 5 ) significantly increase the complexity of the movements when the advanced period doubling scenario, or deterministic chaos, occurs.
  • plates and rammers are devices weighing between 50 and 500 kg, it can be casually said that the smaller the device, the greater the vibration challenge.
  • the ground stiffness k B achieved by a soil compaction device as determined by the soil compaction devices mentioned above can be dispensed with, as long as accurate (exact) ground stiffness values are desired and only an indication is given indicating whether soil rigidity increases or is already satisfactory on further traversal with the device Has achieved value, greatly simplified and thus inexpensive with the following in FIG. 10 shown measuring device 20 are made.
  • Such a measuring device 20 for a Bodensteiftechniksrichtwert will be installed mainly in the already inexpensive vibrating plates.
  • the vibrations of the undercarriage 17 are recorded with an acceleration sensor 21 , amplified by an amplifier 23 and integrated with an integrator 25 over a predetermined period of time.
  • the integration is made from the acceleration value measured with the acceleration sensor 21 after two times Integration to get a way.
  • the output signal of the integrator 25 is fed to a plurality of bandpass filters 27 .
  • the bandpass filter is designed such that once the excitation frequency f, the first harmonic at twice the excitation frequency 2 ⁇ f, the first subharmonic with the half excitation frequency f / 2, the second subharmonic with a fourth excitation frequency f / 4 and the third subharmonic with a achtel excitation frequency f / 8 are transmitted to one output 29a to 29e .
  • the measuring device has four quotient formers 31a to 31d for monitoring the frequencies 2 * f, f, f / 2, f / 4 and f / 8 .
  • the output 29b (output signal to f) is connected as a divisor to all quotient formers 31a to 31d . All outputs are each connected to a quotient generator 31a to 31d .
  • the output 29a (output signal to 2 * f) is connected as a dividend to the quotient generator 31a whose output signal (quotient) is applied to its output 33a .
  • the output 33a is routed via a normalization circuit 35 to two lights 37a in a display panel 39 .
  • the luminaires 37b do not light up even if they are repeatedly driven over with the vibrating plate, further compaction, be it due to the soil composition or the machine data of the vibrating plate used, is not possible. The same applies to the lights 37c and 37d .
  • the maximum amplitude A (f) with the action frequency f is smaller than that A (f / 2) of the first subharmonic f / 2.
  • the expected maximum amplitudes can be read analogously from the "fig tree scenario”.

  • the signals are usually high enough.
  • the signal of the third subharmonic f / 8 is now, since it is usually small, integrated with an integrator 43 and analogous to in FIG. 10 processed. It does not have to be integrated until the third subharmonic f / 8 . It is also possible to integrate the second subharmonic f / 4 or the fourth subharmonic f / 16 (x: factor, x ⁇ 1-2).
  • the sensor for receiving the waveform of the vibration system is arranged according to the above description on the undercarriage 11 or 17 or on the chassis 6 ; he but can also be arranged on the superstructure 9 and 15 respectively.
  • vibration influences due to the damping elements, as outlined above, must be taken into account.
  • the demonstration of the chaotic behavior of dynamically excited compaction devices places the vibration behavior patterns known from various investigations into a common context.
  • the basis is the one-sided bond between soil (asphalt layer) and the oscillating part of the device.
  • the increase in the vibration excitation and / or the increasing rigidity of the soil with increasing compression leads to the periodic lifting of the compactor from the ground.
