摘　　要：对起重机起升机构动载特性进行了分析研究，建立了三质量二自由度的等效扭振系统及相对应的动力学方程组、在建立数学模型的基础上．采用simulink仿真工具箱对起升机构四种典型工况进行了计算机仿真，并与实测特性曲线进行了分析比较、具有一定的工程应用价植。This paper researches dynamic performance of crane hoisting mechanism and establishes a three-mass and two-degrees of freedom equivalent system and its dynamics equations. On the basis of established mathematical model,this paper simulates four typical situations of hoisting mechanism by use of Simulink simulation tool box. The simulation is compared with the testing performance curve,and the result proves that the method presented is valuable for engineering applications.
