摘　　要：利用SIMPACK多体动力学软件建立HXN5型机车模型,研究60轨、60N轨廓形对该机车直线轨道上的动力学性能及曲线通过能力的影响。研究结果表明:运行速度的增大或曲线半径的减小会恶化机车运行性能,机车在直线轨道上的钢轨廓形适应性差异较小,在小半径曲线上60N轨的适应性比60轨更好。The model of HXN5 locomotive was established with SIMPACK multi-body dynamics software,and the influence of 60-track and 60 N-track profile on the dynamic performance and curve passing capacity of the locomotive on the linear track was studied.The research results show that:the increase of operating speed or the decrease of curve radius will deteriorate the locomotive running performance.The rail profile adaptability difference of the locomotive on the straight track is small,and the adaptability of the 60 N rail on the small radius curve is better than that of the 60 rail.
