    摘要:

    以接头类薄壁件为研究对象,针对其在铣削加工中装夹位置的优化设计进行研究。利用UG对四刃立铣刀和零件进行了三维建模。通过有限元分析软件ABAQUS,对不同装夹位置对接头结构件变形的影响进行了模拟。以平均变形量最小为目的,基于MATLAB遗传算法对装夹位置进行了优化计算,确定了最优装夹位置。为航空接头结构件铣削加工中装夹位置对变形的控制提供了有效的方法。

    Abstract:

    By taking the joint thin-walled parts as research object, a kind of research was carried out on the optimization of clamping scheme for the workpiece in milling process. The three-dimensional (3-D) model of fourflute end mill and the workpiece part were made by UG. The effect of different clamping scheme on the deformation of joint structure parts was simulated by the finite element analysis (FEA) software ABAQUS. With the purpose of getting the minimum of the average deformation, MATLAB genetic algorithm was based to optimize the clamping scheme and to acquire the best clamping scheme. The research results provide an effective method for controlling the deformation due to different clamping scheme of aeronautic joint-shaped workpiece.
