Study On Vehicle Crash Simulation Based On Multigen Creator And Vega Prime

Automobile traffic is a complex system composed of people,cars and environment.O nly these three elements work together to make the system give full play to the safety function.In the transportation system composed of Man-Vehicle-Road,as long as the car is still drivied by poeple,traffic accidents can still occur.Therefore,the st udy of the causes of traffic accidents is a complex problem.Virtual reality technology has the characteristics of visualization,human-computer interaction,repeatability,low cost and so on.By using the virtual reality technology,we can carry out the deep and direct representation of the complex accident.Virtual reality technology provides an efficient and energy-saving way to study the causes of traffic accidents.In this paper,the vehicle collision accident is taken as the research object,and Multigen Creator and Vega Prime are used as the platform to build the virtual scene of the vehicle crash scene simulation.The virtual walkthrough and collision simulation of the vehicle are realized.The main contents of this paper are as follows:1.Using MultigenCreator three-dimensional modeling software to establish a three-dimensional model of the vehicle and accident scene environment.The modeling process of vehicle collision scene is analyzed.The modeling technology and optimization technology of Multigen Creator software are discussed in depth,which makes the visual simulation system to achieve the balance between the two aspects of fidelity and real-time.2.According to the vehicle accident scene and the accident identification report,Matlab is used to fit the trajectory of vehicle collision.The position coordinates of each moment in the vehicle collision process are obtained,which provides the vehicle driving data for vehicle collision reconstruction.3.The initial framework of the system is developed by Vega Prime simulation software.To achieve a preview of the scene,the transformation of view.Using Path Tool module to establish vehicle routing.Make different vehicles travel at different times,and realize the collision response.
