Abstract

The invention discloses a body-in-white structure static stiffness test device which comprises a support, a first stand column mechanism and a second stand column mechanism. The support comprises a cross beam and a supporting frame, and the cross beam is rotationally connected to the supporting frame. The first stand column mechanism and the second stand column mechanism each comprise a front suspension installation stand column and a rear suspension installation stand column. The front suspension installation stand column is arranged on the cross beam, the front suspension installation standcolumn comprises a rod piece and a base, the base is arranged on the cross beam, and the rod piece is fixedly connected to the base; the base comprises a connecting plate, a first connecting block anda second connecting block, the first connecting block can rotate or be fixed relative to the connecting plate, the second connecting block can rotate or be fixed relative to the first connecting block, and the rotating axis of the first connecting block is perpendicular to the rotating axis of the second connecting block. The problem that an existing test device is complex in structure for achieving bending and torsion test conversion is solved.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing technology and equipment, in particular to a static stiffness test device for a body-in-white structure. Background technique [0002] The bending stiffness and torsional stiffness of the automobile body-in-white are important technical indicators for evaluating the ability of the body-in-white to resist bending and torsional deformation. They have an important impact on the performance and handling stability of the automobile, which affect the reliability, safety and NVH of the vehicle and other key performances. index. Therefore, the body-in-white structure static stiffness test device is an indispensable equipment for the development of passenger car products, and the test content includes body bending stiffness test and body torsional stiffness test. [0003] However, in order to ensure the constrained state of the body-in-white structure in the existing static stiffness test...
