摘　　要：结合有限元分析软件ANSYS和动力学分析软件ADAMS,对某型固定回转起重机的臂架系统进行突然卸载仿真分析。建立单独的副臂系统动力学模型,通过软件仿真得出臂架在不同工况下突然卸载时的最大后倾角,分析了卸载时间、起重量对臂架系统突然卸载的影响;建立主副臂整体系统动力学模型,分析突然卸载主臂系统与副臂系统耦合的影响。It is in consideration of a finite elements software ANSYS and a kinetic analysis software ADAMS to make a simulated analysis of the jib systemof a stationary derrick crane in terms of its abrupt un-loading. Individual kinetic models were constructed for the jib systemto have got a max back rake when the jib drops suddenly under different working condi-tions, while analyses being done of ihe unloading time, and load lifted, which would affect the jib unloading. Kinetic models have been constructed for the boomand jib as a whole so as to analyze how such an abrupt unloading affects coupling of the boomsystemwith the boomsystem.
