摘　　要：针对矿用无轨胶轮车在井下巷道中出现的碰撞问题,对无轨胶轮车吸能盒结构进行设计并在巷道内进行碰撞分析。基于LS-DYNA仿真平台,对吸能盒进行不同偏置角度的碰撞分析,得出防撞梁与井下墙壁倾角为10°时,碰撞表现最好。对吸能盒引导槽进行优化分析,优化后的吸能盒吸能量增加17.4%,碰撞接触力峰值减少4.8%,对减轻井下无轨胶轮车碰撞事故的危害,指导吸能盒结构设计具有重要参考意义。Aiming at the collision problem of the trackless rubber-tyred vehicles in underground roadway for mine, the energy-absorbing box structure of the trackless rubber-tyred vehicle was designed and the collision analysis in the roadway was carried out. Based on the LS-DYNA simulation platform, the collision analysis for the energy-absorbing box at different offset angles was carried out. It was concluded that the collision performance was the best when the angle between the anti-collision beam and the underground wall was 10°.Then, the optimization analysis of the guide groove of the energy-absorbing box was carried out. After the optimization, the energy absorption of the energy-absorbing box increased by 17.4%, and the peak value of the collision contact force decreased by 4.8%. It was of great reference to reduce the damage of the collision accident of the underground trackless rubber-tyred vehicle and to guide the structural design of the energyabsorbing box.
