【摘要】 针对X轿车的副车架焊接总成在道路试验中经常出现早期破坏的情况,本文应用ADAMS/CAR和NASTRAN等CAE软件对其进行了受力计算和应力分析,分析得到的应力集中部位与道路试验中出现的破坏部位基本吻合,从而为以后的改进设计提供了强有力的理论根据。更多还原

【Abstract】 For the early failure of X car subframe welding assembly during road test, this paper uses CAE software such as ADAMS/CAR and NASTRAN to calculate the force and analyze the stress. The stress concentration spot obtained from the analysis conforms basically with the failure spot occurred in the road test, thus providing strong evidence for future improvement.更多还原
