本文基于对车辆及乘员的安全风险分析,提出车辆减速度即自救车道集料阻力系数为影响车辆及乘员安全风险的直接因素,通过对实际车辆驶入自救车道事故中车辆损坏及乘员心理、惊吓程度等现场调研,车辆车厢强度的计算机仿真分析等方法,提出车辆减速度最大限制为0.5g,即自救车道集料阻力系数在不超过0.5的情况下,不会造成车辆尤其是驾驶室的严重变形,乘员不会碰撞驾驶室内部造成损伤,也不会对乘员心理造成伤害。本文研究成果为更安全的自救车道设计以及我国相关标准规范的编制提供了数据支撑。 Based on the analysis of the safety risk of vehicles and their occupants, this paper puts forward that the vehicle deceleration, ie, the aggregate resistance coefficient of self-help driveway, is the direct factor that affects the safety risk of vehicles and occupants. Through the vehicle damage and crew mentality of actual vehicle entering self- Degree and other field research, computer simulation of the strength of the car compartment and other methods, proposed vehicle deceleration maximum limit of 0.5g, self-help lane aggregate resistance factor of not more than 0.5 in the case, will not cause serious vehicles, especially the cab Deformation, the crew will not collide with the interior of the cabin damage, will not cause psychological damage to the crew. The results of this paper provide data support for safer self-help lane design and compilation of relevant standards in China.
