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.
