This paper, by applying the theory of longitudinal train dynamics, presents an analysis of the impact rules of empty oil tank car marshalled at the end of goods train in lowspeed emergency braking, and discusses the effects of impact speed,characteristic of buffer and height of gravity center of car body upon the vehicle'S pitching angular vibration.
讨论了冲击速度、缓冲器特性、车体重心对车辆点头振动的影响，得出剧烈的纵向冲击引起大幅度点头振动，导致车体后心盘垂直上移与后转向架下心盘错位是造成尾部空油罐车脱轨的主要原因，并对防止此类事故的发生提出了建议。
