摘要
为了对采用变频调速系统后的起升机构进行分析研究,建立了电机模型和三质量二自由度的等效扭振系统及对应的动力学方程,在建立数学模型的基础上,应用SIMULINK仿真工具箱对4种工况进行了计算机仿真,验证了模型的正确性.
A motor model, a three-mass and two-degrees of freedom equivalent system and its dynamics equations are established, in order to research the dynamic performance of craue hoisting mechanism. On the basis of established mathematical model, it also simulates four typical situations of hoisting mechanism by SIMULINK. The validity of the simulation model is tested.
