摘　　要：考虑系统的扭转振动作用,利用Lagrance法建立XK(H)2740数控龙门镗铣床主传动系统的扭转动力学模型。采用MATLAB软件计算了在时变啮合刚度和误差激励下主传动系统的动态响应,验证了主传动系统的动态特性,为机床主传动系统的动态性能优化提供了理论依据。By taking torsional vibration of the system into account, torsional vibration dynamic model of principal transmission system for XK （H） 2740, a CNC gantry boring and milling machine tool, was established by lumped parameter （Lagrance） method. Matlab software was used to calculate the dynamic response of principal drive system during excitation of time-vary mesh stiffness and error. Dynamic character of the principal transmission system was verified. Thus, dynamic optimization for the principal transmission system of a machine tool can be obtained through this theoretic basis.
