The invention discloses a fixed connection device for vehicle body bending rigidity test. The fixed connection device comprises a mounting base structure and a fixed connection mechanism. The mountingbase structure comprises a mounting base and a mounting cover plate, and a limiting cavity is formed between the mounting cover plate and the mounting base. The fixed connecting mechanism comprises arotary disc structure and a connecting rod structure, and the connecting rod structure is used for being connected with a front overhang mounting point. The connecting rod structure has the rotational freedom degree of rotating in the horizontal plane, and the freedom degree of the connecting rod structure in the direction perpendicular to the horizontal plane is zero. Based on the fixed connecting device for vehicle body bending rigidity test, the invention further provides vehicle body bending rigidity test equipment. The fixed connection device and equipment for vehicle body bending rigidity test, which are provided by the invention, aim to solve the problem that in the prior art, the freedom degree of a vehicle body bending rigidity test connection structure is unreasonable, clamps are prone to being stuck, and the test effect is affected.
Description
technical field [0001] The invention belongs to the technical field of automotive equipment, and in particular relates to a fixed connection device for a vehicle body bending stiffness test and vehicle body bending stiffness testing equipment. Background technique [0002] In the process of automobile development, the static torsion and bending stiffness tests of the body-in-white are indispensable links in the vehicle test. The body-in-white stiffness test system generally consists of test benches, loading systems, measurement control systems and other components. Each is different. During the body-in-white stiffness test, the front and rear suspension mounting points of the body-in-white are constrained by fixtures to achieve the purpose of constraining different degrees of freedom. However, most of the body-in-white test devices currently do not have general-purpose fixtures to constrain the mounting points of the front and rear suspensions of the body-in-white, and spec...
