基于西门子S120驱动的高速滚珠丝杠副动态精度测试研究

Study on dynamic accuracy test of high speed ball-screw based on SIEMENS S120 drive

设计开发了一种高速滚珠丝杠副动态精度测试试验台。试验台采用了西门子公司S120伺服驱动系统与基于PC的控制器Win AC通讯的自动化解决方案。建立了滚珠丝杠热变形与运动精度两大动态测试系统,并在自制高速滚珠丝杠副试验台上进行了测试实验,对实验数据结果进行有效的分析,得出了滚珠丝杠副动态精度的影响因素并提出相应的改进措施。

Designing and developing a kind of dynamic accuracy test bench of high speed ball-screw, used an au- tomation solution method of S120 servo system and based on WinAC of PC com-munication. Set up two dynamic test systems of ball-screw thermal deformation and kinematic ac- curacy, then done tests and analyzed the data results, got the dynamic accuracy influence factors of the ball screw and proposed the corresponding measures.
