Modeling and Dynamic Simulation of Heavy-duty Feed Table by Joint Driven

提出了采用电动机驱动丝杠与液压缸联合实现复合驱动进给工作台方式,即电动机驱动实现精确定位,液压系统实现动态卸荷。建立了复合驱动工作台的力学模型,并对模型进行了数值仿真。结果表明,采用复合驱动的方式可实现重载条件下电动机驱动的动态卸荷,可有效解决在重载条件下工作台的精确定位问题。

In order to meet the demands of feeding precision of the feed table with heavy duty, joint driven by compounding of electric motor and pneumatic was presented in this paper. The electric motor droved the feed table with lead screws and the pneumatic loaded off the feed systemdynamically. The joint-driven model was built and the simulation was developed. The analysis indicates that dynamic load -off results form the joint driven can improve the dynamic performance and the feeding precision of the feed table with heavy duty.
