摘　　要：导引头产品某较大型薄壁类零件在车削加工过程中,加工变形大,加工状态不稳定。考虑到影响加工变形的主要因素为切削三要素,现通过AdantEdge FEM及ANSYS-workbench有限元仿真法对薄壁外壳体零件的车削加工过程及模态、谐响应进行仿真分析,通过AdantEdge FEM后处理结果中温度场、应力场及变形的变化情况,对切削参数进行调整,优化切削加工过程,通过ANSYS-workbench对该薄壁模型进行模态分析及谐响应分析,得到工件的加工变形情况,从而采取最优切削加工方案控制薄壁外壳体零件的变形。In the turning process of a large thin-wall part of seeker product,the processing deformation was large and the processing state was unstable.Considering that the main factors that affecting the machining deformation were the three cutting elements,the simulation analysis of the turning process and modal and harmonic response of thin-walled outer shell parts was carried out by using AdantEdge FEM and ANSYS-workbench finite element simulation method.According to the post-processing results situation of temperature field,stress field and deformation changes of AdantEdge FEM,the cutting parameters were adjusted,and the cutting process was optimized.The modal analysis and harmonic response analysis of the thin-wall model were carried out by ANSYs-workbench to obtain the machining deformation of the workpiece,thus the optimal cutting scheme was adopted to control the deformation of thin-walled outer shell parts.
