针对传统设计方法下数控车床夹具尺寸与重量偏大、外型不尽合理,使夹具的材料与应用成本增大的问题,将连续体拓扑优化理论引入数控车床夹具设计,建立了夹具拓扑优化的数学模型,应用有限元分析软件ANSYS,对一种典型轮毂夹具进行拓扑优化设计,给出了夹具外型和联接螺钉的布置区域,得到了更为合理的结构,为各类数控车床夹具的轻量化设计提供了新的思路与参考。
Aiming at the problem that the size and weight of the CNC lathe fixture are too large and the appearance is not reasonable in the traditional design method, the material and the application cost of the fixture are increased. The continuum topology optimization theory is introduced into the design of the CNC lathe fixture. Mathematical model, the finite element analysis software ANSYS is used to optimize the topology of a typical hub fixture. The appearance of the fixture and the layout area of the coupling screws are given, and a more reasonable structure is obtained. As a result, the light weight of various types of CNC lathe fixture Quantitative design provides a new way of thinking and reference.
