Analysis Of The Collision Between The Car And The Second Wheel

In recent years,with rapid increase total diesel locomotive in each region,the rapid extension of the road mileage,road traffic becomes very complex,traffic accidents are becoming more and more serious,has become a serious threat to human life and property safety hazard,with the modernization development of the city,the road congestion is more and more highlights,in order to alleviate the growing motor vehicle ownership and the lagging of roads,parking lots,more and more city vigorously promote green travel,while the second round car travel became the main force of green travel,mobike,OFO bicycle heavily promoted in the major cities,more and more simple way of earning of motorcycle driver's license and convenient for application,in terms of the popularity of fast and simple operation of electric two wheelers,make more and more people give up driving and using two wheels as the main transportation of travel,so two horse by researchers gradually become urban traffic accident is one of the most vulnerable transport users.As the two car accidents increase gradually,the accident characteristic such as diversity,complexity and instantaneity,more and more traffic accidents by judicial authentication is needed to restore the process of the accident.In traffic accidents in the process of judicial authentication,if only according to the basic principles of mechanics,with the original method to calculate the important parameter for the traffic accident were analyzed,and makes the result accuracy is low.With the progress of high-end computer technology and computer simulation technology development,the traffic accident reduction using mature software,through the parameter simulation method for simulating road traffic accident reappearance,become the main development direction of traffic accident research.How to calculate the speed of the accident vehicle by using the data of the accident scene,and improve the accuracy of the calculation,and become the main content of this study.In this paper,design different speed of car collision with two wheels after the body thrown distance,two wheels threw the first collision point distance and the relationship between the distance,using the linear regression equation by throwing away from the regression equation of the motor speed can be calculated,and through the actual case to verify the feasibility of the regression equation.This thesis mainly study content is as follows:This paper analyzes the types of collision between cars and the second wheel and the corresponding theoretical calculation methods.The type of collision between the car and the second wheel is roughly divided into head-on collision,side impact,tail collision and crowded collision.Application of PC-Crash software to build a model of vehicle collision with a second-wheel vehicle.Through the specific vehicle type,the corresponding car database and the two-wheel multi-rigid-body model of the PC-Crash software are applied to build the vehicle and the common four kinds of two-wheel car Crash course.Analyze the regression equation of the car head-on collision.By using the method of linear regression,the regression equation of the second wheel was obtained by using the Excel regression tool.The feasibility of the equation is verified by using the equations of the two wheelers.
