摘要/Abstract

摘要：

针对高精度数控机床直接驱动进给系统动力学特性易受机械部件弹性变形、电气系统控制参数影响的特点,从机电耦合角度出发,用有限元法将永磁直线进给工作台进行柔性化,应用拉格朗日-麦克斯韦方程建立直线进给系统多柔性体的机电耦合模型。结合有限元分析软件ANSYS、动力学仿真软件ADAMS建立直线进给系统多柔性体的机电耦合仿真模型,并对系统进行动力学仿真分析和实验验证。结果表明,工作台柔性化更接近真实的工作情况;电气控制参数对系统动力学特性有显著影响。直线进给系统多柔性体机电耦合模型的建立可为直接驱动系统结构优化设计提供依据。

Abstract:

The dynamic characteristics of high-precision CNC machine direct drive linear feed system were affected by mechanical component elastic deformations and the electrical system control parameters susceptibly. From the viewpoint of electromechanical coupling,direct drive linear feed table flexible electromechanical coupling model was established using the finite element method and Lagrange-Maxwell's equations. Combined with the finite element analysis software ANSYS, dynamic simulation software ADAMS, linear feed system flexible electromechanical coupling simulation model was established. Then the system dynamics simulations were analyzed using this simulation model. The analysis shows that the flexibility feed table is up to the real situation, and electrical control parameters have a significant effect on the system dynamics. Linear feed system flexible electromechanical coupling model can provide evidence for direct drive system structure optimization design.

Key words: direct drive, electromechanical coupling, dynamics, permanent magnet synchronous linear motor, high-precision CNC machine
