摘要

运动系统是数控成形机实现其基本功能的关键部件,同时也是影响其加工精度最主要的部件。首先对成形机的运动系统开展机械结构设计,依据轻量化设计原则,对其关键部件Y轴和Z轴采用了铸铝材料,并将其设计为具有轻质支撑型芯和大面积惯性矩的三明治结构。然后通过有限元数值模拟方法对其进行了结构静力学和模态分析,并进行了工程验证,最后研究得知运动系统在刚度和强度方面均能满足成形机的使用要求和许用条件。

Abstract

The moving system is the most critical part of numerical control（ NC for short） forming machine to achieve its fundamental function,but also the most importent part that affect the processing accuracy. The moving system of forming machine were lightweight designed firstly. Based on lightweight design principles,aluminum material was adopted on its key components of Y and Z axis,and the sandwich structure which has advantages of lightweight core and large inertia moment. Then structural static analysis and mode analysis of moving system were done by using the method of FEM numerical simulation,and the engineering verification was carried out. Results of the study show that the strength and stiffness of the moving system can satisfy the use requirement and allowable conditions of the forming machine.
