摘　　要：承受冲击和扭振载荷的核心部件主传动装置,直接影响到宽厚板轧机轧制生产效率。有限元模拟计算结果表明,扁头叉头与轴相过渡的圆角处为轧机主传动装置容易发生疲劳损伤的位置;4700mm宽厚板轧机主传动装置轧制侧接轴叉头的模拟使用寿命为2.79年;与轧机发生断裂事故位置及实际使用寿命高度吻合,对生产实际提供基础理论指导。The main transmission device, the core component bearing the impact and torsional vibration load, directly affects the production efficiency of wide and heavy plate mill. The finite element simulation results showed that the fillet of the transition between the flat fork head and the shaft is the location where the fatigue damage of the main transmission device of the rolling mill is easy to occur;The simulated service life of the main drive of 4700 mm wide and thick plate mill is 2.79 years;It is highly consistent with the fracture accident location and actual service life of the rolling mill, and provides basic theoretical guidance for production practice.
