Abstract

In order to more accurately simulate the injury of riders and the motion characteristics of two-wheelers, the modeling method and the simulation model of two-wheeler traffic accidents are studied in this paper. Firstly, the rider dummy model is established by using the module combination method. Then, taking into account the manipulation of riders on two-wheelers and the interaction between the two-wheeler and the road, the hand grip model and the two-wheeler model are established respectively. On this basis, a rider-two-wheeler-road coupled system model is proposed. The analysis of driving dynamics shows that the coupled model has good motion stability. The coupled model is applied to the simulation of real two-wheeler accident. The simulation results are consistent with the on-site monitoring videos and investigation reports, which verified the feasibility and effectiveness of the modeling method.

摘要

为了更准确地模拟骑手的伤害和两轮车的运动特性，本文对两轮车交通事故的建模方法和仿真模型进行了研究。首先，采用模块组合方法建立骑手假人模型。然后，考虑到骑手对两轮车的操控以及两轮车与路面的相互作用，分别建立了手握模型和两轮车模型。在此基础上，提出了骑手-两轮-路耦合系统模型。行驶动力学分析表明，耦合模型具有良好的运动稳定性。将耦合模型应用于真实两轮车事故的仿真。模拟结果与现场监测视频和调查报告一致，
