摘要:
汽车后副车架多为焊接件，为防止焊缝失效，焊接工艺设计和对关键焊缝的识别显得尤为重要。以某 SUV 后副车架为例，利用有限元拓扑优化技术识别出该后副车架关键焊缝，针对关键焊缝形态进行焊接工艺优化，并对其进行疲劳耐久台架试验验证。结果表明，优化后的后副车架能顺利通过台架及路试，满足整车疲劳耐久安全需求。
Abstract:
The rear subframe of automobile is mostly welded. In order to prevent weld cracking, the design of welding process andthe identification of important welds are particularly important. Taking the rear sub-frame of a SUV as an example, the key welds of therear sub-frame were identified by using the finite element topology optimization technology, and the welding process was optimizedaccording to the key weld morphology, and the fatigue endurance test was carried out to verify it. The results show that the optimizedrear sub-frame can pass the bench and road test smoothly and meet the fatigue and durability safety requirements of the vehicle.
