Description
Technical field
The utility model belongs to stiffened panel compression test field, and a kind of stiffened panel compression test testpieces add load control is specifically provided.
Background technology
Stiffened panel compression test is for testing stiffened panel, to bear the test of the ability of compressive load, is exerted pressure in the stiffened panel test specimen two ends of test, until the failure conditions such as unstability, conquassation appear in stiffened panel.In process of the test, testing machine institute imposed load has larger impact with respect to the offset of the stiffened panel section type heart to test findings.The boundary condition at stiffened panel carrying two ends, as free boundary, clamped border etc., also has certain impact to test findings.So, if effectively control load offset and boundary condition will reduce the accuracy of test findings.
At present, in general stiffened panel compression test, stiffened panel test specimen is simply placed on up and down between testing table of testing machine, and the two ends of testpieces directly contact with testing table.When test is carried out, by the testing table up and down of testing machine, directly to testpieces, exerted pressure.Because testpieces directly contacts with testing table, the offset of the load that testpieces bears and homogeneity are unmanageable.The boundary condition of testpieces can only be also a kind of situation of free boundary condition in addition, can not simulate the various operating modes that run in stiffened panel actual bearer process, this has just lowered the accuracy of test findings, and also cannot the load-bearing capacity of testing experiment part under different boundary conditions.
Utility model content
The purpose of this utility model is to provide a kind of stiffened panel compression test testpieces add load control, is used for fixing testpieces controlled loading condition, and offset and boundary condition that especially can control load, can effectively address the above problem.
The technical solution of the utility model is: stiffened panel compression test testpieces add load control, comprising: test specimen clamper 1, adjustable force transfer bracket 2, hold-down support 3, elastic steel sheet 4, connection bearing 5; Described adjustable force transfer bracket 2 lower surface both sides are equipped with hanger I, described hold-down support 3 upper surface both sides are equipped with hanger II, the hanger I of described adjustable force transfer bracket 2 is connected by connection bearing 5 with the hanger II of hold-down support 3, in the middle part of described adjustable force transfer bracket 2 lower surfaces with between hold-down support 3 upper surface middle part, by elastic steel sheet 4, be connected, described adjustable force transfer bracket 2 tops are connected with test specimen clamper 1 by bolt.
Preferably, described test specimen clamper 1 top is groove structure, conveniently clamps test specimen 6, prevents that test specimen 6 from dropping.
Between described test specimen clamper 1 and test specimen 6, interfix, load is passed to test specimen uniformly.
Described adjustable force transfer bracket 2 interfixes by bolt with test specimen clamper 1, but the relative position between them can be mutually adjusted, by the relative position between adjustable force transfer bracket 2 and test specimen clamper 1, force action line that just can control load makes its section type heart position of passing through testpieces, thereby reaches the object of control load offset.
Described adjustable force transfer bracket 2 is connected with elastic steel sheet 4 by connection bearing 5 with hold-down support 3, and hold-down support 3 is fixed on testing table.By connection bearing 5, connect and make the load of transmitting between adjustable force transfer bracket 2 and hold-down support 3 only by the plane of symmetry of adjustable force transfer bracket 2, pass to testpieces.
Described elastic steel sheet 4 parallels with longitudinal plane of symmetry of adjustable force transfer bracket 2, and its effect is to transmit moment of flexure between hold-down support 3 and adjustable force transfer bracket 2, the boundary condition that Control experiment part loads.While not connecting elastic steel sheet 4, be the free boundary situation of testpieces, be replaced by 4 loadings that can simulate clamped border of elastic steel sheet of rigidity.
The utlity model has following useful effect:
The utility model can be controlled the offset of institute's imposed load in stiffened panel compression test, improves the accuracy of test findings; Can simulate different test boundary conditions, the load-bearing capacity of test stiffened panel test specimen under different situations.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, stiffened panel compression test testpieces add load control, comprising: test specimen clamper 1, adjustable force transfer bracket 2, hold-down support 3, elastic steel sheet 4, connection bearing 5; Adjustable force transfer bracket 2 lower surface both sides are equipped with hanger I, institute's hold-down support 3 upper surface both sides are equipped with hanger II, the hanger I of adjustable force transfer bracket 2 is connected by connection bearing 5 with the hanger II of hold-down support 3, in the middle part of adjustable force transfer bracket 2 lower surfaces with between hold-down support 3 upper surface middle part, by elastic steel sheet 4, be connected, adjustable force transfer bracket 2 tops are connected with test specimen clamper 1 by bolt.
Test specimen clamper 1 top is groove structure, conveniently clamps test specimen 6, prevents that test specimen 6 from dropping.Between test specimen clamper 1 and test specimen 6, interfix, load is passed to test specimen uniformly.
Adjustable force transfer bracket 2 interfixes by bolt with test specimen clamper 1, but the relative position between them can be mutually adjusted, by the relative position between adjustable force transfer bracket 2 and test specimen clamper 1, force action line that just can control load makes its section type heart position of passing through testpieces, thereby reaches the object of control load offset.
Adjustable force transfer bracket 2 is connected with elastic steel sheet 4 by connection bearing 5 with hold-down support 3, and hold-down support 3 is fixed on testing table.By connection bearing 5, connect and make the load of transmitting between adjustable force transfer bracket 2 and hold-down support 3 only by the plane of symmetry of adjustable force transfer bracket 2, pass to testpieces.
Elastic steel sheet 4 parallels with longitudinal plane of symmetry of adjustable force transfer bracket 2, and its effect is to transmit moment of flexure between hold-down support 3 and adjustable force transfer bracket 2, the boundary condition that Control experiment part loads.While not connecting elastic steel sheet 4, be the free boundary situation of testpieces, be replaced by 4 loadings that can simulate clamped border of elastic steel sheet of rigidity.The elastic steel sheet 4 by replacing with different elastic propertys regulates the boundary condition that puts on test specimen.
While carrying out stiffened panel compression test, as shown in Figure 2, at testpieces 6 two ends, two add load controls are installed respectively, two add load controls are connected to a fixed with the testing table up and down of testing machine respectively.Test specimen 6 is installed on the centre of two add load controls, bears the load of two ends test unit.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
