摘要: 分析了汽车碰撞交通事故抛物体研究进展,包括行人、骑车人和自行车模型。对各数学模型的研究现状、存在的问题和发展前沿进行了论述。本文作者利用PCCrash建立虚拟仿真碰撞试验场,对应不同车辆类型,分别建立了车辆—行人侧面碰撞、后部碰撞,刮擦碰撞和自行车/骑车人仿真抛距模型。传统的抛距模型中,车辆在发生碰撞时通常会采取制动措施,本文对车辆不采取制动的碰撞形式也进行了分析和仿真,建立了车辆行人高速碰撞模型,上述工作对车辆行人事故再现研究的发展具有一定指导意义和实用价值。

Abstract: In this paper,several technologies are introduced and analyzed in accident reconstruction,including pedestrian,bicyclist and bicycle models,in which the research actuality,existent problems and progress status of the mathematical model ale also scientifically scrutinized and dissertated.Analog collision test ground of vehicle/pedestrians is conducted by PC—Crash,according to various vehicle styles,vehicle/pedestrians side collision,and rear collision,scrape collision as well as bicycle/bicyclist collision throwing distance model is established in the paper to simulate the test data.In conventional throwing models,it usually employs brake when the vehicles collide,while the situation that driver doesn’t put on the brakes in car-pedestrian collision accident is also analyzed in this paper,as well as the vehicle/pedestrians high collision model is approached.At the same time,the paper will play certain guidance significances for advance in term s of traffic reconstruction research field.

Key words: accident reconstruction, throw distances, simulation, crash experiment
