摘要
装夹是生产制造过程中必须面对的首要问题。装夹布局设计是否合理,对工件的加工精度、质量以及企业的生产安全和效率都至关重要。为此使用基于正交设计的多方法融合的方法进行装夹布局的设计进行优化。首先,建立装夹稳定性数学模型来判断工件是否稳定;接着使用ANSYS进行建模并与遗传算法进行接口的操作;然后,针对人为设置的遗传算法参数,采用正交试验设计的方法选择更好的遗传算法参数;最后以壳体薄壁件为例进行试验,得到了更小的装夹变形和更加合理的装夹布局,从而提升工件的加工精度和质量。
Clamping is the essential process for manufacturing.The reasonable design of is a crucial factor for enterprise in terms of either the workpiece quality and machining accuracy,or safety and efficiency of production.Therefore,this chapter is aimed at to optimize the design of clamping layout by use of the multi-method fusion based on orthogonal design.Firstly,to establish the clamping stability mathematical model to judge whether the workpiece is stable or not.Secondly,to execute model establishment and use ANSYS and genetic algorithm interface operation by means of ANSYS.Then,the orthogonal experimental design method is adopted on this chapter to select better genetic algorithm parameters.Finally,the shell thin-walled parts are taken as an example to conduct the test,and smaller clamping deformation and more reasonable clamping layout are obtained,the machining accuracy and quality of the workpiece are heightened.
