At the same time, analyze the welding deformation of straight-line segment model of side rail, and compare the results with test data, verify this method is efficient.
同时，针对汽车纵梁部分直线段模型进行焊接变形分析，并与试验数据进行了对比，验证了该方法的有效性。
2
The acquired data can reflect the factual welding process rightly, furthermore, the welding process can be well repeated by using the welding parameters.
采集的数据能正确反映焊接实际过程，焊接参数经还原后可实现焊接过程参数的可追溯性。
