The sub-structure method is used to divide the main drive system of Yantan Shiplift into several sub-systems, and the dynamic model of each sub-system is established and then connected into the overall dynamic model.In the modeling process, the rigid damping The torque and friction moment of each bearing are put in the force matrix according to nonlinear process.The dynamic response is calculated by Wilson -θ method and programmed by MATLAB5.3.Under normal conditions, the load carrying capacity of 1.8m from the high cabin to the low Start the operating conditions of the point of dynamic simulation
