摘　　要：采用四因素三水平的正交试验方法对60 kg/m重轨的水平矫直规程进行了优化,通过ANSYS Workbench软件中的显式动力模块Workbench LS-DYNA进行了重轨水平矫直过程的数值模拟分析,针对矫后轨底的参与拉应力指标进行统计学分析,得出了重轨水平矫直的最优矫直规程,从而提高矫直质量,对现场生产有着重要参考以及指导作用.A orthogonal test of four factors and three levels was adopted to optimize the horizontal straightening procedure of 60 kg/m heavy rail.The numerical simulation of horizontal straightening process of the heavy rail was carried out through the Workbench LS-DYNA of explicit power module in ANSYS Workbench software.And the statistical analysis was carried out using the residual stress after straightening as an indicator.Then the optimal horizontal straightening rule was obtained to improve the quality of straightening,providing an important reference for the field production.
