摘　　要：针对以往对交流电机驱动的轧机主传动系统振动特性的研究往往忽略电气参数影响这一问题,考虑交流异步电机中串联补偿电容、转子电阻、相位延时、谐波扰动等电气因素,然后结合机械系统,建立了交流电机驱动的轧机主传动系统机电耦合振动数学模型,并用数值方法研究了串联补偿电容、转子电阻、相位延时、谐波扰动等电气因素对轧机主传动系统振动特性的影响。研究结果为进一步分析、诊断及控制交流驱动的轧机主传动系统的振动现象奠定了理论基础。Aiming at this problem that the previous researches of vibration characteristics for the main drive system of rolling mill about Alternating Current（ AC） ignored considering the effects of electrical parameters, an electromechanical coupling mathematical model about vibration for the main drive system of rolling mill about AC is established,which considers the series capacitors in power network,the rotor resistance,the phase delay,the harmonic disturbances and other electrical factors of the AC asynchronous motor that combines the mechanism system. The effects about the series capacitors in power network,the rotor resistance,the phase delay,the harmonic disturbances and other electrical factors on the vibration characteristics in the main drive system of rolling mill are studied by numerical analysis. The research conclusion establishes further theoretical basis to analyze,diagnose and control vibration phenomenon in the main drive system of rolling mill about AC.
