摘　　要：通过对后车架制造过程工艺流程的分析,识别可能影响后车架扭曲变形的流程,利用工序验证和仿真分析获取影响扭曲变形的关键因素,通过调整焊接顺序和改造设备控制关键因素,显著改善了后车架扭曲变形问题,并在工厂内部推广使用,减少了因后车架扭曲变形而进行返修的概率。Through the analysis of the manufacturing process flow of the rear frame,the flow that may affect the distortion of the rear frame is identified,and the key factors that affect the distortion are obtained by the verification and simulation of the working procedure,by adjusting the welding sequence and modifying the key factors of the equipment control,the distortion of the rear frame is obviously improved,and is popularized in the factory to reduce the probability of repairing the rear frame due to distortion.
