摘　　要：宽带钢轧机辊间接触压力分布直接影响辊面疲劳硬化和磨损状态,进而影响支承辊的使用寿命。采用有限元法对辊间接触压力分布进行了模拟分析,在此基础上开展了辊形优化设计,并以改善接触压力分布均匀性、缩短支承辊边部有害接触区为目标,得到了优化的支承辊辊形参数。Fatigue hardening and wear of roll surface were affected directly by the contact pressure distribution between work roll backup roll for wide strip mill,which brought an obvious effect to service life of backup roll.An optimum design on profile of backup rolls was developed based on contact analysis of backup roll using FEM.Homogenized contact pressure and shortened length of harmful contact were as main aims,and the optimized parameters of profile of backup rolls were obtained.

关 键 词：支承辊 接触分析 辊形优化设计 辊间接触压力均匀化
