针对航空接头薄壁件存在的加工变形问题,提出了辅助支撑提高工件刚度的方法,实现对航空接头类薄壁件加工变形的控制.运用有限元法,在有、无辅助支撑的两种情况下,对典型接头薄壁件铣削加工过程进行模拟仿真,并获得加工后零件的变形数据.通过对比得知辅助支撑能够有效的改善薄壁件的加工变形,对进一步研究航空接头类薄壁件铣削加工变形具有指导意义.

According to the existing the machining deformation of aviation joint thin-walled parts,proposes the methods of auxiliary support improves stiffness to implement the control of machining deformation of avi-ation joint thin-walled parts.In both cases with and without auxiliary support,using the finite element method to simulate the typical joint thin-walled parts milling process,and obtain the deformation data of processed parts.From the comparison,it can be concluded that auxiliary support can improve the machining deforma-tion of thin-walled parts effectively ,and provide help to further research on the deformation of aviation joint thin-walled parts.
