| Abstract: | The process of twist beam fatigue failure reproduction is presented based on the fatigue life prediction of seam weld,and improvement method is conducted.The correlation among simulation/bench test and road test is built up through the validation of bench test and vehicle road test,which can reduce the development cycle,save the development cost and improve the product quality. |
