| 摘 要： | 分析高速龙门机床中应用双直线电动机驱动同步进给轴的优越性。给出了基于SIMUERIK 840D的Gantry龙门同步功能控制双直线电动机高速同步驱动的实现方法。探讨通过应用双频激光干涉仪测量动态同步误差方法,并在自构建的龙门驱动实验台上,对主从轴的动态同步误差进行测试实验。测试结果表明:在Gantry控制驱动下,主从轴的动态同步误差随进给速度增大而增大;不同的龙门负载会在直线电动机加速和减速阶段对同步性能产生影响。

| Abstract: | The advantages of dual linear motors drive system in high speed feed gantry-moving machine are analyzed. Based on the Gantry Axes function of SIMUERIK 840D, a synchronized control method of dual linear motors with high feed rate is presented. Then the method of test the dynamic synchronous error of Gantry Axes by using laser interferometer is studied, and the dynamic synchronous error of Gantry Axes is tested on gantry-moving testing machine. The results indicate that the synchronous error becomes larger as... |
