摘 要: 提出了交流拖動繞線式三相電動機串聯(lián)多段電阻控制下的加速過程箕斗提升機電系統(tǒng)動力學的時變且非線性的模型,并在此基礎(chǔ)上,借助計算機仿真技術(shù),分別得到了八段和六段串聯(lián)電阻下的提升容器與滾筒的運動學與動力學規(guī)律。作者提出的力學模型和方法以及所揭示的一些未見報道的現(xiàn)象和規(guī)律對于舊式提升機的改進尤其是改用計算機控制具有重要參考價值,對其它形式的交流拖動或直流拖動提升設(shè)備設(shè)計或改進也具有一定的參考價值。

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.
