The paper introduces the current methods and their defect about testing the dynamic parameters of air-static pressure main shaft system,and advances a new method,namely,the measurement method of the end swing value of shaft,the axial movement value of shaft and the axis drift value of shaft,etc.

阐述了现行的测试空气静压主轴系统动态参数的方法及其不足,在此基础上提出了一种新的测试方法,即:测量主轴的端面偏摆量、轴向窜动量、轴心漂移量等方法。
