摘　　要：以零传动滚齿机YK3610为例,针对加工系统建立弹簧系统动力学模型,并以此通过分析建立其加工系统的数学模型;运用动态测试系统对加工系统的模型进行试验研究,试验数据表明,该模型可预测该滚齿机加工系统动力学固有性能,而且可以通过优化主轴,改善主轴刚度的方式来提高加工系统的动态特性。为了改善滚齿机床加工系统的动态特性,保证滚齿机加工精度,最后提出了提高零传动加工系统刚度的基本措施。The direct-drive gear hobbing machine tool YK3610 is being discussed. The dynamics model of spring system is built for the machining system, and then the mathematics model for it is also built by analyzing the spring system. Then the experiment research on the model of the machining system was performed. The results indicate that the model can predict the irmer performance of the machining system in direct-drive gear hobbing machine tool. And the improvement on the dynamics characteristic can be done by optimizing the rigidity of the spindle. Finally, the advices on improving the dynamics performance of the machining system are given in order to assure the precision.
