摘　　要：利用ANSYS软件对刚度因素引起的误差变量进行了筛选和测量,并考虑其在运动过程中发生的变化,根据多体运动学理论,建立静态误差数学模型。将理论误差量与实际测量误差量相对比,验证了此建模方案是可行的,为机床静态误差建模提供了新的参考方向。The error variable caused by the factor of stiffness was filtered and measured by using ANSYS software,meanwhile its changes occurred in the process of movement were considered. Then mathematical model of this static error is established according to multi-body kinematics theory. The errors of theoretical and actual measurement were compared to validate that this model scheme is feasible,which provides a new reference direction for modeling of static error for the machine.
