空白的材料性质在与横向的内部肋骨旋转铝合金部分的过程的电源上有大效果。由使用有限元素( FE )和 Taguchi 方法,五个关键材料参数的效果和意义,也就是在内部肋骨的 formability 上的厚度方向,收益力量,变硬的代表,加强的因素和有弹性的模量的各向异性的索引,墙骨折和完成的旋转部分的不同类的变丑的度的趋势被获得。成就为选择合理旋转材料提供一个重要指南,并且为最佳设计和与横向的内部肋骨旋转部分的过程的力量的精确控制是很重要的。
Material properties of blank have a great effect on power spinning process of aluminum alloy parts with transverse inner rib. By using finite element(FE) and Taguchi method, the effects and significance of five key material parameters, namely, anisotropic index in thickness direction, yield strength, hardening exponent, strengthening factor and elastic modulus on the formability of inner rib, tendency of wall fracture and degree of inhomogeneous deformation of finished spun parts were obtained. The achievements provide an important guide for selecting reasonable spinning material, and are very significant for the optimum design and precision control of power spinning process of parts with transverse inner rib.
