摘　　要：从弹性力学理论出发,引入弹性接触问题来描述碰撞过程,根据弹性力学、材料力学以及理论力学的基本原理和解决问题的基本思路,对矿车跑车碰撞过程中的碰撞时间和撞击力进行分析研究。以揭示矿车与挡车装置的碰撞机理,为跑车防护装置的合理设计提供参数和依据。From the theory of elasticity, introduce a flexible contact to describe the process of the collision, according to elasticity, mechanical theory and the basic principles of mechanics and problem- solving basic ideas, running under the tub collision course time of the collision and impact analysis study. To reveal the tub and the installation of block car collision mechanism for the protective devices racer reasonable parameters and design basis.
