某摩托车零件拉深深度大、表面形状复杂,造成了零件成形时部分区域出现了变形不充分的缺陷,极大降低了零件的强度和刚度,从而导致零件在使用过程中的安全性降低。利用有限元软件对零件成形过程进行了数值模拟分析,利用交互作用正交试验选定成形时的压边力、摩擦系数以及压边力与摩擦系数交互作为影响因素。以零件成形时的变形不充分率作为目标,通过方差分析得出各个因素的显著程度,得到一组最优参数组合。它有效地减少了零件成形时的变形不充分率。
A motorcycle deep drawing depth, the surface shape of the complex, resulting in the formation of parts of the deformation of the inadequate part of the defect, which greatly reduces the strength and rigidity of the parts, resulting in parts of the safety in the use of reduced. The forming process of the part was simulated by finite element software. The interaction of the blank holder force, the friction coefficient, the blank holder force and the friction coefficient were selected as the influencing factors by the orthogonal test of the interaction. To the part of the deformation of the inadequate rate as a goal, through the analysis of variance obtained significant degree of each factor, get a set of optimal combination of parameters. It effectively reduces the deformation of the part forming the inadequate rate.
