摘　　要：针对目前煤矿斜井运输中矿车跑车的实际问题,求碰撞瞬时最大力是设计的难点,现在的计算方法主要是经验化、静态化,难以真实反映实际情况。在分析其他方法的基础上,创新地运用能量法解决了这一难点,并对跑车的动力学进行了必要的分析。Deals with tramcars escape practical problem in inclined tunnel transportation, the most difficult is instantaneous collision maximal stress. The current calculation method is experienced, static, so it is not true reflection of the actual situation. After analysing the other methods, solve the difficult by energy meth- od, and analyse the dynamics about tramear escape. So the research has certain effect on the practice.

关 键 词：斜井跑车 碰撞 瞬时最大力 能量法 运动响应
