The paper is based on rotational parts of a kind of Screen Press machine tool. In order to guarantee the kinematics precision and stability of large rotational part, the technology of dual servo motor synchronous dive is adopted instead of conventional hydraulic servo drive. In order to analyze and predict the performances of the driving system, firstly, geometry models of the driving systems are created and assembled by three dimensional CAD software. Afterwards, the kinematical simulations of the driving system are done by the multi body dynamic analysis method. Various drive schemes are simulated and analyzed. It will also give essential references to the further design and production.
