摘要
在DKJ-08C生瓷带打孔机运动平台动态测试的基础上,建立了运动平台的有限元模型,并应用有限元软件对其进行模态分析。通过调整导轨跨距的方法,对运动平台的机械刚度进行优化。结果表明增加运动平台导轨跨距,可以有效地抑制平台沿移动方向的扭转振动,提高系统的机械带宽。
On the basis of the DKJ-08C punching machine dynamic test,a finite element model of the motion platform is established.Finite element analysis software is used to analyze the modal characterize of the motion platform.By adjusting the guide span,the mechanical stiffness of the motion platform is optimized.The result shows that increasing the guide rail span of the platform can effectively restrain the torsional vibration of the platform along the moving direction and improve the mechanical bandwidth of the system.
