为了实现椭圆孔的加工,采用欧拉法对轴心运动轨迹进行控制仿真。提出了一种新型静压支承和液压控制系统,研究了期望轴心坐标与电液伺服阀阀芯位移之间的定量关系。采用欧拉法对轴心开环控制轨迹进行了仿真。仿真结果表明,开环控制方法不仅能控制轴心运动形成椭圆轨道,而且对动态干扰力或瞬时静态干扰力具有较强的鲁棒性。为椭圆孔的加工提供了理论依据。
In order to realize the machining of elliptical holes, the article researches control simulation of shaft center movement orbit using Eulerian method. A new hydrostatic bearing and a hydraulic control system are proposed, and quantitative relation between the expected shaft center coordinates and spool displacement of electro-hydraulic servo valve is studied. With the Eulerian method, open-loop control orbit of shaft center is simulated. And the simulation results indicate that open-loop control method not only controls shaft center movement to form ellipse orbits but also has strong robustness against dynamic disturbing force or instantaneous static disturbing force. This article lays theoretical basis for machining of elliptical holes.
