摘要

本研究的目的是调查行人和骑自行车者的着陆运动学(LK)，并提供影响因素的分析。分析了112例行人和51例骑自行车者的视频信息。结果表明，行人和骑自行车者的着陆运动学取决于车辆的前端形状和撞击速度。在此LK1中，行人/骑自行车者的身体在接触地面时具有明显的旋转速度。在这种情况下，71%的骑自行车者和39%的行人头部首先接触地面。在最常见的LK2中，行人/骑自行车的人被向前抛出，然后在没有旋转速度的情况下落地(占所有行人的46%和所有骑自行车的49%)。研究车辆车头形状与行人/骑自行车者的LK之间的关系，可以指导机动车辆的安全设计，降低头部损伤的风险

Comparison of the landing kinematics of pedestrians and cyclists during ground impact determined from vehicle collision video records

The purpose of this study was to investigate the landing kinematics (LK) of pedestrians and cyclists and to provide an analysis of the influencing factors. A total of 112 pedestrian cases and 51 cyclist cases with video information were analysed. The results showed that the pedestrians' and cyclists' landing kinematics depends on the vehicle front-end shape and impact velocity. In this LK1, the pedestrian/cyclist body had a clear rotation speed during ground contact. In this case, 71% of the cyclists and 39% of the pedestrians were found head firstly contact to the ground. In the most frequent LK2, the pedestrian/cyclist was thrown upward-forward and then landed without rotational speed (46% of all pedestrian and 49% of all cyclist cases). Research on the relation between the vehicle front shape and the LK of pedestrians/ cyclists can guide the safety design of a motor vehicle for reducing head injury risk

期刊介绍： The IJVS aims to provide a refereed and authoritative source of information in the field of vehicle safety design, research, and development. It serves applied scientists, engineers, policy makers and safety advocates with a platform to develop, promote, and coordinate the science, technology and practice of vehicle safety. IJVS also seeks to establish channels of communication between industry and academy, industry and government in the field of vehicle safety. IJVS is published quarterly. It covers the subjects of passive and active safety in road traffic as well as traffic related public health issues, from impact biomechanics to vehicle crashworthiness, and from crash avoidance to intelligent highway systems.
