摘　　要：为验证不同种类的交通事故现场处置车辆在不同的停放方式下对交通事故现场的防御效果,采用PC-Crash 12.0中文版软件设计了一种仿真实验。通过模拟误闯入交通事故处置现场的车辆与防御车辆的碰撞,以防御车辆被误闯入车辆撞击后沿道路前进方向运行的距离作为防御效果的评价指标,运行的距离越短,防御效果越好。仿真结果表明:大型车辆的防御效果要明显优于小型车辆;当防御车辆一定时,最佳的防御角度随误闯入车辆的速度增加而减少;当误闯入车辆的速度位于中速(50 km/h)时,防御车辆与道路前进方向的夹角在30°左右时防御效果最佳。A simulation experiment is designed by using PC-Crash 12.0 Chinese software to verify the defense effect of different kinds of vehicles in different parking modes for traffic accident scenes.The collision is stimulated between the intruding vehicle and the vehicle in the defensive position in the experiment.The running distance along the road after the vehicle in the defensive position is hit is taken as the evaluation index of the defending effect.The smaller the running distance,the better the defending effect.The simulation results show that the defense effect of a truck is obviously better than a car;when the defense vehicle is fixed,the optimal parking angle decreases with the increase of the speed of the intruding vehicle;when the speed of the intruding vehicle is at the medium speed(50 km/h),the defense effect is the best when the angle between the defense vehicle and the road forward is about 30°.
