摘要
指出了磨床的进给运动采用直线电动机驱动系统较之传统的滚珠丝杠形式具有一系列的优点。分析了摩擦力、磨削力、力波动对机床进给系统的影响。通过相关的物理学理论,建立了进给系统的动力学方程,在此基础上建立了摩擦力、磨削力、力波动的数学模型,从而为进给系统数学模型作了基础性工作。该项研究为未来直线电动机驱动系统在磨床上的广泛应用具有指导性意义。
This paper shows that the grinder incorporated with linear motor driving system is superior to the traditional one with lead screw transmission mechanism. It also analyzes the influence of friction force, grinding force and force fluctuation on the feed mechanism of the grinder. By relative physical theory, the dynamical equation of feed system is set up. Then mathematical model of friction force, grinding force and force fluctuation are all established, thereby making the foundation for establishing mathematical model of feed system. This study is helpful to the wide application of linear motor driving system to the grinder in the future.
