Anti-seismic loading device for rigid testing and using method thereof

Abstract

The invention provides an anti-seismic loading device for rigid testing. The device comprises a rack (5), a loading trolley (9) which is arranged on the rack (5) and can move left and right and a clamping table (11) which is fixed at the left end of the rack (5) and is used for clamping a workpiece (1), wherein an external threaded sleeve (7) is fixedly connected to the right side of the loading trolley (9), is used for extending into the hollow inside of a rotating shaft (6), and is in threaded fit with an inner threaded annular part (71) at the left end of the rotating shaft (6); the right end of the rotating shaft (6) is dynamically connected with the output shaft of a drive motor (8) which is arranged on the right side of a lug boss (51) of the rack (5); a damping cushion (86) is arranged at the bottom of the drive motor (8); a reinforcing rib (87) is arranged between the damping cushion (86) and the lug boss (51); and the damping cushion (86) is used for reducing the shaking force generated when the drive motor (8) runs, so that the running stability of the drive motor (8) is improved.

Description

technical field [0001] The invention relates to the field of material testing equipment, in particular to an anti-seismic loading device for rigidity testing and a method for using the same. Background technique [0002] The rigidity test of the material is an important index for the material performance of the workpiece. Materials may deform differently under different loads and thus exhibit different stiffness properties. Some existing testing equipment continuously applies gradually increasing loads to materials and measures the amount of deformation that occurs during the process. Due to the dynamic nature of load changes and the immediacy of measurement, this method is prone to cause measurement errors. For equipment with fixed value applied load, due to the discreteness of fixed value, it is difficult to obtain the point performance of expected value at any time. Moreover, slight fluctuations in the load are prone to occur during the hold of a fixed value, resulting...
