Abstract

The invention discloses a fixed connection device for a vehicle body bending stiffness test, comprising: a mounting seat structure and a fixed connection mechanism. The mounting seat structure includes a mounting base and a mounting cover, and a limited cavity is formed between the mounting cover and the mounting base; the fixed connection mechanism includes a turntable structure and a connecting rod structure, and the connecting rod structure is used for connecting Suspension installation point; the connecting rod structure has a rotational degree of freedom to rotate on a horizontal plane, and the degree of freedom of the connecting rod structure in a direction perpendicular to the horizontal plane is zero. In the fixed connection device for the above-mentioned vehicle body bending stiffness test, the present invention also provides a kind of vehicle body bending stiffness test equipment. The setting of the degree of freedom of the connection structure is unreasonable, and it is prone to the problem that the clamp is stuck and the experimental 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...
