轿车白车身弯扭静刚度试验方法研究

Research on Test Method of Bending Torsional Static Stiffness of Car Body in White

随着汽车人均保有量的增加,人们对汽车舒适性的要求越来越高,轿车车身刚度是影响整车舒适性的重要指标之一,同时它还影响汽车的安全性能。在汽车车身开发阶段,各大车企都会测试自己所开发车型的白车身刚度情况。文章主要分析了白车身弯扭刚度试验结果影响因素以及各试验方法的差异性,为后续的车身开发者提供一点思路与建议。

With the increase of car ownership per capita,people have higher and higher requirements for vehicle comfort.Car body stiffness is one of the important indicators affecting the comfort of the vehicle,and it also affects the safety performance of the car.In the stage of auto body development,all major car companies will test the stiffness of their developed models in BIW.This paper mainly analyzes the influence factors of BIW bending and torsion stiffness test results and the differences of various test methods,and provides some ideas and suggestions for the follow-up body developers.
