Study on Electromechanical Coupling Vibration Characteristics of Main Drive System of Rolling Mill Considering Motor Impact
摘要
Abstract
Aiming at the problem of rolling mill main drive system vibration researches,such as ignoring the influence of asynchronous motor itself,in this paper,considering asynchronous motor magnetic flux leakage coefficient,the stator time constant,rotor time constant and the nonlinear factors of rotors air friction,and putting the air friction into the rolling mill main drive system,the AC motor-rolling mill main drive system of electromechanical coupling model is established.The influences of the asynchronous motor magnetic flux leakage coefficient,the stator time constant,rotor time constant and the air friction coefficient to amplitude and adjusting time of main drive system were analyzed by numerical method.关键词
