摘　　要：以某12 m全承载式客车为研究对象,进行正面碰撞下的结构耐撞性分析。针对驾驶员及上层前排乘客生存空间侵入严重的情况,在前端增加吸能盒,并采用正交试验设计的方法对其进行改进。结果表明,驾驶员及上层乘客的生存空间均得到保证,两处的碰撞加速度值分别降低18%和61%。Taking a 12 meter monocoque coach as the research object, the authors analyzs the structural impact resistance under the frontal impact. In view of the serious incursion situation of the driver and the upper front passenger survival space, they increase the energy absorbing box at the front end, and use the method of orthogonal experiment design to improve the structure. The results show that the survival space of the driver and the upper passengers are guaranteed, the acceleration values of the above two positions are decreased by 18% and 61% respectively.
