通过网格应变分析技术 ,对某轿车采用一次成形、两次成形工艺冲制减振器座的应变状态进行了定量研究 ,结果表明 ,成形工艺对减振器座的应变分布、应变路径、应变大小影响很大 ,一次成形较两次成形对材料的成形性能要求较高 ,两次成形工艺更有利于零件成形 Through the grid strain analysis technique, the quantitative research on the strain state of a shock absorber seat made by one-time molding and two-time forming process is carried out. The results show that the strain distribution, strain path, strain The size of a great impact, forming a more than two forming the material forming performance requirements are higher, two forming process is more conducive to the formation of parts
