Embodiment Construction

[0030] In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0031] The gist of the present invention is, by carrying out fatigue test to automobile whole vehicle or other spare parts to existing bench test device, especially for the analysis of the fatigue test demand of assembly part and single piece, find that existing bench test device is in rigidity Insufficiency in adjustment, especially the different direction adjustment of stiffness, makes it difficult for the stiffness of the fixture on the bench test device to approach the stiffness of the installation point during the fatigue test, resulting in the poor effect of the fatigue test. A simple structure is provided, which not only The stiffness of the bench test device can be adjusted conveniently, especially the bench test device which can conveniently adju...

Abstract

The invention provides a rack experimental device with adjustable rigidity and a rigidity adjusting method thereof in order to solve the problem that the conventional rack experimental device has a bad fatigue test effect on the whole automobile or other parts of the automobile. According to arrangement of bolts and fastening nuts corresponding to bottom support through grooves and base through grooves and the setting of height of a supporting cylinder, the rigidity of the rack experimental device can be conveniently adjusted, particularly the rigidity can be adjusted in different directions, so that a fatigue test state accords with an actual operating state of the automobile body and the other parts of the automobile, the precision and effect of the fatigue test of the automobile body and the other parts of the automobile are greatly improved, and an accurate experimental validation guidance is provided for the design of the automobile and the parts.

Description

technical field [0001] The invention relates to the technical field of fatigue testing of complete automobiles and components, in particular to a bench test device with adjustable stiffness and a stiffness adjustment method thereof. Background technique [0002] Fatigue test is a theoretical study aimed at the continuous performance degradation or even destruction of a certain product or component caused by repeated work within a limited period of time. This test can collect and analyze the reasons for the "aging" and "deterioration" of the product. The key parameters provide a large amount of rare experimental data for the innovative research of designers, effectively ensure the quality of product design, and shorten the R & D assessment cycle. [0003] At present, the fatigue test of the whole vehicle or parts of the car usually adopts a bench test device, and the corresponding fixture is set on the bench test device to clamp the whole car or other parts to be tested, so a...
