摘　　要：为分析轧机传动系统的动态力学行为,利用能量等效方法对宝钢1 580 mm热连轧线F2轧机主传动系统建立了10阶离散线性力学模型,采用目前成熟的模态分析法解耦系统方程,并用龙格库塔方法求解各解耦后的方程,得到系统的固有频率和咬钢冲击引起的扭矩放大系数(TAF),并采用应变片实测了轧机动态扭矩,两者吻合较好。To analyze the rolling mill drive torsional oscillation,a 10-order discrete linear mechanical model was established for the F2 mill main drive of 1 580 mm hot strip rolling line in Baosteel,by using energy equivalent method and modal analysis theory.Then the decoupled system equations were solved by using Runge-Kutte method,the results fit well the measured torque and torque amplification factor.
