热带钢连轧机主传动系统的动态研究

Dynamic Study on Main Drive System of Hot Continuous Strip Mill

确立了某热带钢连轧机主传动系统的扭振动力学模型,用拉格朗日方程建立了扭振数学模型,用m atlab计算软件求出了系统固有频率和振型,用系数法求出了扭矩放大系数,讨论了频率放大系数对扭矩放大系数的影响。

Torsional vibration dynamics model for main drive system of a hot continuous strip mill is established. Torsional vibration mathematical model is determined by Lagrangian equation, the intrinsic frequency, vibration type of the system and torque multiplication ratio are respectively calculated by matlab computing software and coefficient method. Influence of frequency multiplication coefficient on that of torque is discussed.
