摘    要:提出了交流拖动绕线式三相电动机串联多段电阻控制下的加速过程箕斗提升机电系统动力学的时变且非线性的模型,并在此基础上,借助计算机仿真技术,分别得到了八段和六段串联电阻下的提升容器与滚筒的运动学与动力学规律。作者提出的力学模型和方法以及所揭示的一些未见报道的现象和规律对于旧式提升机的改进尤其是改用计算机控制具有重要参考价值,对其它形式的交流拖动或直流拖动提升设备设计或改进也具有一定的参考价值。

Abstract: The time-variant & nonlinear dynamic model for the mechanical-electrical system of the skip winding equipment being accelerated was put forward firstly, in which an AC motor was controlled through multi-pieces of resistances in series. On the basis of the model and by using computer simulation technique, the kinematic & dynamic laws of the winding vehicles and the winding engine with 8-pieces and 6-pieces of resistances in series were gotten respectively. The proposed model and ways as well as the discovered phenomena and laws are fresh and can be the theoretical basis of improving the old type of winding system, especially the one improved with computer control technique, and it is helpful greatly to design other forms of winding system driven by AC motors or DC motors.
