摘要： 目的以真实案例为基础,研究自行车与机动车碰撞交通事故中,不同机动车型、交通方式等因子造成自行车骑车人下肢内侧骑跨伤的特征,分析其生物力学机制。方法选取上海地区发生的自行车与机动车碰撞交通事故案例140例,全面收集现场、自行车、机动车、人体、交通方向等信息,运用回顾性研究方法分析,同时,选取其中典型案例,通过计算机仿真技术模拟事故发生过程,提取人体各受伤部位的动力学响应数值,如加速度、力和力矩等,与案例研究结果对比。结果全部事故中出现骑跨伤与无骑跨伤案例频数相等;侧面撞击与前后方向撞击骑跨伤的发生情况无显著性差别;大型车辆撞击事故中出现骑跨伤频率较低;骑跨伤的发生频率随车速加大而增高;就骑跨伤的分布来说,撞击侧下肢骑跨伤位置低(链条、脚蹬管等损伤),而对侧骑跨伤位置高(鞍座损伤),在小型车辆撞击时该特点更明显。结论分析自行车骑车人的骑跨伤特征和生物力学机制有望对道路交通行为方式鉴定提供新依据。

Abstract: Objective To study the characteristics and biomechanical mechanism of riding injuries involving bicycles collided by motor vehicles. Methods The real traffic accident cases of bicycles collided by motor vehicles, including the information of scenes, bicycles, motor vehicles, rider wounds and traffic directions, were collected. Retrospective method was used to study these riding injuries. In addition, typical cases were selected to simulate traffic accident courses with computer simulation software, and the dynamic data like acceleration, force, moment were extracted to compare with those in the real cases. Results There were no difference of occurring frequency between cases with or without riding injuries, as well as between one-side-collision and front-or back-collision. The riding injuries seemed less in accidents involving large-scale vehicles. The frequency of riding injuries increased with vehicle speed. The wound location was low on collision side and high on opposite. Conclusion Analysis of riding injury characteristic in traffic accidents and their biomechanical mechanism would be helpful for estimation of traffic manner.
