摘　　要：轧机主传动系统是轧制过程中传递运动和力矩的主要装置,其扭转振动(扭振)是影响钢铁生产质量并导致关键零部件异常破坏的重要原因之一。基于ANSYS有限元软件,针对轧机主传动扭振系统进行数值模拟及结构失效分析。首先,对轧机主传动系统进行模态分析,获得扭振系统固有属性关系;然后,通过谐响应分析得出不同位置零部件的频域响应曲线;最后,对易损部位关键零部件件进行结构失效原因分析,将数值计算结果与实际情况相结合,以验证分析结果的准确性与可靠性。研究结果可为轧机主传动扭振系统中零部件结构优化和进一步动态控制策略的制定提供重要理论参考。The main drive system of rolling mill is the main device of transmitting motion and torque,and the torsional vibration is one of the important factors that affect the quality of steel production and lead to abnormal damage of key parts.Based on ANSYS software,the numerical simulation of main drive torsional vibration system and structural failure analysis are carried out.First,the modal analysis of main drive system is made,and the inherent attribute of torsional vibration system is obtained.Next,the harmonic response dynamics of main drive system is analyzed,and the frequency response curves of the key parts in different positions are shown.Finally,the structural failure cause of damageable parts is analyzed,the numerical results are combined with the actual situation to verify the accuracy and reliability of the analysis results.The results may provide an important theoretical reference to optimize the key parts of main drive system and to further formulate dynamic control strategy.
