| 摘 要： | 在分析刀具与工件在装配模型中位置关系的基础上,将平行运动载荷与转动载荷同时施加到刀具模型上,建立了刀具次摆线运动的铣削有限元模型。为了减少模拟的时间,使用过渡网格划分技术对模型进行了优化处理。在考虑工件材料性能参数基础上,利用有限元平台ABAQUS软件,研究了航空铝合金薄壁件铣削过程中铣削力的变化规律。模拟结果基本符合实际,说明有限元模型是正确的,对后续研究工作有一定的参考意义。

| Abstract: | To analyze the relative position between tool and workpiece in assembling model,loading the tool with parallel motion and rotation at the same time,a finite element model for tool milling based on trochoid motion was built.In order to decrease the simulation time,the finite element model was optimized with advanced meshing method.By considering performance parameter for the material of workpiece,the changing rule of milling force on the aeronautical thin-walled workpiece was researched by FEM platform ABAQU... |
