摘要

轧机主传动系统作为传递运动和力矩的主要装置,是一个复杂的机电系统,其机电耦合因素是导致轧机扭振异常变化的重要原因之一。此主要研究轧机主传动系统扭转振动的动力学分析,对比分析不考虑电机与考虑电机反馈的主传动系统扭振,从机理分析机电系统的固有属性;然后建立直流电机驱动下的轧机主传动扭振系统力学模型和数学模型;再采用Matlab/Simulink仿真,对主传动扭振系统失稳状态进行研究,进而分析不确定性参数对轧机主传动系统扭振的影响。研究结果可为进一步揭示轧机扭振系统的振荡规律以及控制策略的制定奠定理论基础。

Abstract

The main drive system of rolling mill is a complicated electromechanical system,as the main device of transmitting motion and torque. The factor of electromechanical coupling is one of the important reasons for the abnormal variation of torsional vibration. The paper mainly researched that the dynamic analyses of the torsional vibration of main drive system of rolling mill. Comparative analysis the torsional vibration of main drive system is obtained between considering electromechanical coupling and not considering electromechanical coupling. Then,the mechanical and mathematical models of the main drive torsional vibration system are established. Based on Matlab/Simulink simulation,the unstable state of the main drive torsional vibration system is used to be studied,and then the influences of the uncertain parameters on the torsional vibration of main drive system are analyzed. The results could be revealed the oscillation law for the torsional vibration of main drive system of rolling mill and provided a theoretical foundation for the formulation of control strategy.
