Abstract
The utility model is a device for a motor vehicle roll-over test. The device comprises a test stand body, a hydraulic system, a measurement system, an anti-side slipping mechanism and a test stand body pedestal. The test stand body is also provided with an acquisition system which can compensate and correct the temperature drift generated by an electronic component. The beneficial effects of the device are that: the acquisition system which can dynamically compensate and correct the temperature drift generated by the electronic component is arranged on the test stand body; the zero-point automatic tracking technology is integrated in a test process; based on the characteristic that the temperature drift of the electronic component is slow in change, the periodic observation is carried out on measurement values in measurement and control software; and based on the measurement characteristics of the measurement values, the impacts of temperature drift of the electronic component on a system test are effectively solved and the test precision is raised.
Description
Technical field
The utility model belongs to a kind of pick-up unit, and definite saying is to belong to a kind of motor vehicle to roll test unit.
Background technology
At home, have minority manufacturing enterprise all to develop the vehicle roll testing table, what have sells in market.These equipment are to promoting technical progress of industry to play positive impetus, but also Shortcomings part, be mainly manifested in: (1) device integration is not high.For realize weighing, inclination, barycenter test, rollover roll these several test functions, even need to use the above equipment of three covers.(2) measuring accuracy is inadequate.A lot of testing apparatuss all ignored weigh, in the inclination, barycenter test process, it also is that detection device for combination property is turned in a kind of passenger car side canting of saying that its publication number of Chinese patent CN202057495 is arranged, this device to test precision is high, the advantages such as convenience, but do not consider that tested vehicle can be on the testboard bay long period in process of the test, because the temperature of electronic component is floated characteristic, in long-time measuring process, can exert an influence to measurement result, affect measuring accuracy.
The utility model content
The purpose of this utility model just provides a kind of motor vehicle and rolls test unit, solving tested vehicle is on the testboard bay because of the long period in process of the test, because the temperature of electronic component is floated characteristic, in long-time measuring process, can exert an influence to measurement result, affect measuring accuracy.
A kind of motor vehicle of the present utility model rolls test unit, comprise test-bed body, hydraulic system, measuring system and anti-side-slipping mechanism and test-bed body pedestal, it is characterized in that: on described test-bed body, also be provided with and float the acquisition system that compensates and revise to the temperature that electronic component produces.By at test-bed body acquisition system being set, in test process, incorporate automatic tracking technique at zero point by acquisition system, according to electronic component temperature driftization characteristics slowly, in TT﹠C software, measured value is periodically observed, according to measurement characteristics measured value is revised, effectively solve the electronic component temperature and float the impact that system testing is brought, improve measuring accuracy.
Further, described acquisition system has adopted automatic tracking technique at zero point, can float the measuring error of bringing to the electronic component temperature and compensate dynamically and revise.It is easy and simple in structure to collect data by such being arranged so that, and zero point, automatic tracking technique can reduce the error that the reasons such as electronic component temperature rise are brought measuring system.
Further, described sensor setting is on the back end of test table top.The data of measuring are accurate.
Further, described measuring system comprises the support column that supports test-bed body four ends, is provided with weighing plate at described support column, is provided with 4 LOAD CELLS at each weighing plate.Put the realization kinetic measurement by the present invention, and data communication device crossed network cable transmission to master system, to tested motor vehicle is carried out lifting, TT﹠C system is carried out real-time monitoring to the weight change of four wheels and the angle of stand in the process of lifting, algorithm by upper computer software carries out analysis and calculation to these real-time measurement values, the multiple measuring abilities such as realization is weighed, maximum roll stable angle, rollover, barycenter measurement.
Further, described measuring system also comprises the angular transducer that is arranged on the test-bed body lower end, and described angular transducer is 2.Carry out analysis-by-synthesis and draw more accurate angle of inclination by angle is detected.
Beneficial effect
The beneficial effects of the utility model are to float and dynamically revise and compensate by the temperature that electronic component is produced is set at test-bed body, in test process, incorporate automatic tracking technique at zero point, according to electronic component temperature driftization characteristics slowly, in TT﹠C software, measured value is periodically observed, according to measurement characteristics measured value is revised, effectively solve the electronic component temperature and float the impact that system testing is brought, improve measuring accuracy.
