Abstract

To obtain a rider-vehicle-road coupling system that takes both efficiency and accuracy into account, so that the simulation model of two-wheeled vehicle traffic accident can reduce the calculation time as much as possible on the premise that it can simulate human biomechanical injury and vehicle deformation, this paper proposes a new two-wheeled vehicle accident simulation model. In this method, the vehicle uses the Facet model, and the cyclist uses the hybrid human model. The coupling system of rider-vehicle-road is established and the effectiveness of the system is verified. For the collision accident between the car and two-wheeled vehicle, the simulation model is used to reconstruct in MADYMO. The results show that the motion posture of cyclists and vehicles after the collision is consistent with the accident situation, and the human injury data is consistent with the medicolegal expertise, which verifies the feasibility and effectiveness of this simulation model. This modelling method provides a new idea for the reconstruction of two-wheeled traffic accidents and the general dynamic simulation.

摘要

获得兼顾效率和精度的人-车-路耦合系统，使两轮车交通事故仿真模型在模拟人体生物力学损伤的前提下，尽可能减少计算时间和车辆变形，本文提出了一种新的两轮车辆事故仿真模型。在这种方法中，车辆使用 Facet 模型，骑车人使用混合人体模型。建立了人-车-路耦合系统并验证了系统的有效性。针对汽车与两轮车的碰撞事故，采用仿真模型在MADYMO中进行重建。结果表明，碰撞后骑车人和车辆的运动姿态与事故情况一致，并且人体损伤数据与法医专业知识一致，验证了该仿真模型的可行性和有效性。该建模方法为两轮交通事故的重建和一般动力学仿真提供了新的思路。
