摘　　要：推导了数控机床进给伺服系统的综合数学模型,包括机械传动部分数学模型、电机模型和刚度模型,构建了包括刚度、非线性间隙和非线性摩擦的参数化结构图,为获取系统的动态特性如最大进给加速度、最大进给速度、定位精度、加工零件精度等提供了一定的理论分析依据。The synthesis mathematical model of servo feed system for NC machine tool were derived, including the mathematical model of mechanical transmission, the model of electromotor and stiffness. The parametric structural drawing were constructed, including stiffness, non-linear gap and non-linear friction. The theoretic and analysis basis for obtaining system dynamic characteristics including maximum feed acceleration and speed, position precision, machined parts precision was provided.
