摘　　要：基于焊接专用数值分析软件SYSWELD,模拟了铝合金电动自行车车架前管和连接管的钨极惰性气体保护焊接(GTAW)过程。基于模拟结果,分析了热应力的形成、演变规律和影响因素,并预测了室温状态时的残余应力分布。研究结果可为铝合金自行车架实际焊接生产中制定残余应力的防治措施提供有益的理论指导。The welding process of GTA welded aluminum alloy electric bicycle flame was numerical simulated by special welding finite element analysis software SYSWELD. Based on the simulation results, the formation, evolution and influence factors of thermal stress were analyzed, and the distribution of residual stress at room temperature was predicted. The results can provide useful theoretical guidance to the development of residual stress prevention measured in the actual welding of aluminum alloy bicycle frame.
