摘　　要：本文论述了数控重型卧式车床纵向采用静压导轨、静压蜗母齿条传动时,机械传动链的最小综合刚度值、固有频率及位置环开环增益等参数的计算方法;定量分析了位置环系统的稳定性。经实践验证,计算方法切实可行,有一定的指导意义。This article discusses the calculating methods of minimum overall rigidity, innate frequency and openloop increment of mechanical transmission chain for the CNC heavy-duty lathe adopting hydrostatic guideway and hydrostatic worm gear and rack,and analyzes the stability of position loop system quantitatively. It has practically been proved that the calculating method is feasible and significant.
