摘　　要：在分析钢轨铣磨车作业原理的基础上,对钢轨铣磨车的铣削刀组进行建模,并利用最优化理论及最小二乘法原理,计算出目标轮廓为60 N钢轨轮廓时钢轨铣磨车的铣削轮廓和铣削精度;建立铣削精度评价指标,从铣削范围、铣削刀粒数量、铣削刀粒样式和分段点设定等多角度,对钢轨铣磨车的铣削刀组进行优化,从理论上提高了钢轨铣磨车的铣削精度;计算出目标轮廓为60 N钢轨轮廓时铣削刀组的优化结果,给出优化后铣削刀组中铣削刀粒的空间布局。Based on the working principle analysis of rail milling train, this study describes the model of the milling cutter group of rail milling train, and calculates the milling profile and the milling accuracy of it when the target profile is 60 N rail profile by using optimization theory and least square method. Also, the milling accuracy evaluation index is established, and the milling cutter group of rail milling train is optimized from multiple aspects, such as the milling range, the number of milling cutter, the style of milling cutter, the set of the piecewise point. In theory, the milling precision of rail milling train is improved. At last, this study gives the optimization result of the milling cutter group when the target profile is 60 N rail profile, and presents the spatial layout of the milling cutters which form the optimized milling cutter group.
