白车身疲劳耐久仿真分析

White body fatigue simulation analysis

某汽车企业研发某款车型在进行可靠性道路试验过程中,车身后部的后尾梁钣金处发现开裂现象,此问题出现,影响车身耐久性能评估。通过道路信号采集、有限元疲劳耐久仿真软件,对此问题进行开裂原因分析,并根据开裂因素制定更改方案,保证该款车型满足疲劳耐久仿真及可靠性道路试验性能评价目标。

During the reliability road test of a certain automobile model developed by an automobile enterprise, cracks were found in the sheet metal of the rear tail beam of the automobile body, which affected the durability evaluation of the automobile body. Through road signal acquisition and finite element fatigue endurance simulation software, cracking causes are analyzed, and modification schemes are formulated according to cracking factors to ensure that the vehicle meets the performance evaluation objectives of fatigue endurance simulation and reliability road test.
