Abstract

The present invention relates to a vehicle body stiffness simulation system for suspension testing, comprising: a base provided with a beam; at least one bracket assembly comprising three brackets, wherein the top of each bracket is fixed to the beam , and the bottom is provided with one or more springs and additional components preloaded towards said springs, said springs being arranged to provide the vertical stiffness at the position to be simulated of the suspension system attached to the vehicle body , the preload is used to provide the torque generated by the suspension system at the position. The invention has a simple and compact structure and is easy to realize, can quickly and efficiently simulate the vertical stiffness and bending stiffness of the vehicle body, and thus has good practicability and reliability.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle body rigidity simulation system for suspension tests, which can be used for suspension system durability tests. Background technique [0002] In the development of automobile suspension system, it is necessary to carry out structural durability test on the suspension system. Such tests will be used to simulate the loading of the suspension system during road testing. The suspension system is installed on the body, because the body has a certain rigidity, but the body-in-white was not provided in the early stage of project development, and the price of the body-in-white was expensive. In order to carry out the suspension test in the early stage of the project, it is necessary to design a device system to simulate the stiffness of the vehicle body for the suspension test, especially for the subframe without bushings, it is particularly important to simulate the stiff...
