Abstract

A flexible integrated test system of dynamic and static properties of a combination automotive body-in-white comprises a portal frame, a support restraint device, an adjustable concentrated force loading device, a torsion pendulum frame loading device and a measuring appliance assembly. The support restraint device for supporting the automotive body-in-white to be tested is fixed on the portal frame, the measuring appliance assembly is fixed on the portal frame by a support or directly fixed on the portal frame, the adjustable concentrated force loading device and the torsion pendulum frame loading device which loads stress on the automotive body-in-white to be tested are fixed on the portal frame or arranged on the peripheral side of the portal frame. The flexible integrated test system of dynamic and static properties of the combination automotive body-in-white has the advantages of simple and compact structure, reasonable layout, convenient operation, comprehensive function, wide application and good expansibility.

Description

technical field [0001] The present invention mainly relates to the field of automobile body-in-white performance testing equipment, in particular to a combined dynamic and static performance flexible comprehensive test system of automobile body-in-white, which can be used to detect the strength, stiffness, natural frequency, ride comfort, moment of inertia, Various dynamic and static performances such as crash safety and fatigue characteristics. Background technique [0002] The performance of the car is manifested in many aspects. The body-in-white of the car is the supporting frame of the whole car. Its performance occupies a large proportion in the performance of the car and is one of the most important technical indicators in the performance of the car. Considering the functional characteristics, safety, lightweight, appearance and other requirements of the car, the structure of the body-in-white has become very complicated. It is a combination of thin steel plates rivet...
