The flip hoisting of nuclear power module adopts cooperative operation mode of crane and crawler flip platform.In order to realize the automatic and following hoisting of crawler flip platform,the hydraulic system model of the crawler flip platform was built in AMESim,and the mechanical model of the crane and crawler flip platform was built in ADAMS.The reason of the unsynchronization in the collaborative hoisting process was analyzed,the PID controller was introduced,and the machinehydraulic joint simulation was realized based on the FMU interface.The simulation results show that setting reasonable PID control parameters can achieve the purpose of synchronous control and meet the requirements of engineering design.
