【摘要】:現(xiàn)代交通運輸業(yè)的快速發(fā)展,使人們的出行方式發(fā)生了很大的改變,居民汽車擁有量逐年增長。隨著汽車擁有量的迅猛增長,道路也因為車流量以及車流密度的增加而越來越擁堵,隨之而來的車輛追尾碰撞事故日漸突出。汽車在給人們帶來方便和快捷的同時,也威脅著人們的生命和財產(chǎn)安全。同時,交通事故處理的公正性和公平性也考驗著相關部門。大多數(shù)的追尾事故,兩車并不是對心碰撞,在事故發(fā)生之后,現(xiàn)場留下的車輛軌跡比較復雜,兩車并不是做一維運動,因此亟需新的方法對偏置追尾事故進行分析。本文在實際追尾事故案例的基礎上,根據(jù)追尾事故的特點,從駕駛?cè)、車輛、道路和環(huán)境角度分析了追尾事故發(fā)生的原因。建立了4種典型的追尾事故碰撞類型,利用仿真軟件PC-Crash,分別對不同相對速度、不同偏置度下的4種碰撞類型進行仿真分析。分別對四種追尾碰撞類型中駕駛?cè)酥苿雍娃D(zhuǎn)向兩種操作行為下,車輛的運動行為進行了仿真,獲得追尾事故中車輛運動參數(shù)。以偏置度、相對速度等作為自變量,速度、加速度、角速度等運動學參數(shù)作為因變量,通過軟件仿真模擬,系統(tǒng)分析自變量與車輛運動行為間的關系。同時根據(jù)再現(xiàn)結(jié)果的不確定性,改變參數(shù)數(shù)據(jù),輸入仿真參數(shù),分析車輛運動行為的變化特征。研究結(jié)果將為駕駛?cè)说男袨闆Q策、事故再現(xiàn)以及車輛的安全設計提供理論依據(jù)。
[Abstract]:With the rapid development of modern transportation industry, people's travel mode has changed greatly, and the number of car ownership has increased year by year, with the rapid growth of vehicle ownership. Because of the increase of traffic flow and traffic density, the road becomes more and more congested, and the vehicle collision accident becomes more and more prominent. The vehicle brings convenience and speed to people at the same time. At the same time, the fairness and fairness of traffic accident handling is also testing the relevant departments. Most of the rear-end accidents, two cars are not to the heart of the collision, after the accident. The track of the vehicle left on the scene is more complex, the two vehicles do not do one-dimensional movement, so it is urgent to use a new method to analyze the bias rear-end accident. This paper is based on the actual case of the rear-end accident. According to the characteristics of the rear-end accident, the causes of the rear-end accident are analyzed from the point of view of the driver, vehicle, road and environment. Four typical collision types of the rear-end accident are established, and the simulation software PC-Crash is used. Four collision types with different relative velocities and different bias degrees were simulated and analyzed respectively. The motion behavior of the vehicle is simulated to obtain the vehicle motion parameters in the rear-end accident, such as bias, relative velocity as independent variables, velocity, acceleration, angular velocity and other kinematics parameters as dependent variables. Through the software simulation, the relationship between independent variables and vehicle motion behavior is analyzed systematically. At the same time, according to the uncertainty of the reappearance result, the parameter data is changed, and the simulation parameters are input. The research results will provide theoretical basis for driver's behavior decision, accident reappearance and vehicle safety design.
