Abstract

The invention provides a passenger vehicle body-in-white joint rigidity measuring device which comprises: a gantry frame, a beam bracket assembly which is mounted on the gantry frame through a beam mounting seat, an air cylinder which is mounted on the beam bracket assembly through an air cylinder bracket and a rod end bearing, a torsion load transfer device and a crankle load transfer device which are fixedly mounted on the lower side of the beam bracket assembly, a joint mounting seat and a joint mounting seat support which are arranged at the bottom of the gantry frame and a torsion beam which is connected with the torsion load transfer device. The passenger vehicle body-in-white joint rigidity measuring device provided by the invention is used for carrying out relevant studies on the rigidity performance of the joint structure, can effectively reduce the complexity of rigidity measurement on the body-in-white structure, and saves the measurement time, improves the efficiency and lowers the labor cost; moreover, the device has the advantages of simplicity and easiness in operation and adaptability to multi-platform vehicle bodies and multiple joint types.

Description

technical field [0001] The invention relates to the field of automobile manufacturing measurement, and in particular to a stiffness measurement device for a body-in-white joint of a passenger car. Background technique [0002] The body stiffness characteristics reflect the ability of the body to resist torsional and bending loads as a whole. It is one of the important evaluation indicators of automobile performance and directly or indirectly affects the sealing performance, ride comfort, handling stability, and reliability of the body structure of the vehicle. And durability and body dynamic characteristics. The T-shaped joints on the car body and other load-bearing parts together form a solid car body load-bearing structure. Factors such as the structural characteristics of the joints and the characteristics of the key sections of the car body have a decisive impact on the structural performance of the car body. In addition to the stiffness analysis, the stiffness analysis...
