Finished automobile rigidity experiment bench and clamping method of experiment bench

Abstract

The invention discloses a finished automobile rigidity experiment bench. The finished automobile rigidity experiment bench comprises a front overhang bench (1) and a back overhang bench (2). The finished automobile rigidity experiment bench is characterized in that the front overhang bench (1) comprises a front left bracket assembly (11), a front right bracket assembly (12), a front overhang bench cantilever assembly and a regulating mechanism (13) and a front overhang bench support base assembly (14). The back overhang bench (2) comprises a back left bracket assembly (21), a back right bracket assembly (22), and a back overhang bench overall beam and a regulating mechanism (23), wherein the back left bracket assembly (21) and the back right bracket assembly (22) are respectively arranged on the left side and the right side of the back overhang bench overall beam and a regulating mechanism (23). Compared with the prior experiment bench, the finished automobile rigidity experiment bench does not need to clamp repeatedly in the process of conversion of a torsion test and a bending test, and only needs to regulate 3 corresponding control pins to finish the conversion. The clamping method of the experiment bench is simple, convenient and small in labor intensity.

Description

technical field [0001] The invention relates to the technical field of engineering testing, in particular to a vehicle stiffness test bench and a bench clamping method. Background technique [0002] With the demand for localization of automobile development, whether the rigid technical indicators of body structure design can meet the design requirements, the only way to judge it is to draw conclusions through rigidity tests. The body-in-white rigid test bench is an indispensable test equipment in the development of automobile products. Through the results of test test data, it can timely reflect the defects and weak points in the design, provide a basis for design modification, and ensure the design quality of products. , to shorten the product development cycle and save development costs. [0003] Due to the relatively specific scope of application of the body rigidity test bench, the body rigidity test benches of each user unit are non-standard test benches designed and m...
