Problems solved by technology

[0002] In the existing demonstrative forms of analyzing motor vehicle accidents, there is no realistic report on the results of simulating the scene of motor vehicle collision accidents. The simulation form of motor vehicle collision scene is for analysts with different needs to judge the situation of motor vehicle collision scene in different situations. For example, accident appraisers can use this method to analyze and judge the situation of traffic accident scene and make judgments on accident responsibility

Embodiment

[0043] The processing steps of the present embodiment include:

[0044] (1) Build the computer simulation system first, then set the motor vehicle collision parameters to be simulated at the scene, and input these parameters into the computer simulation system, select the type of collision and confirm it, and then start the computer simulation system;

[0045] (2) The computer simulation system automatically calculates the collision parameters of the motor vehicle, and judges and analyzes the collision parameters;

[0046] (3) First judge whether a collision can occur, if the judgment result is yes, then go to step (4); if the judgment result is no, go to step (1);

[0047] (4) The computer simulation system automatically calculates and determines the position coordinates of the colliding motor vehicle, and performs analysis and calculation according to the position coordinate parameters of the motor vehicle;

[0048] (5) The computer simulation system automatically calculate...

Abstract

The invention belongs to the technical field of motor vehicle collision accidents and relates to a motor vehicle collision accident simulation method. The method comprises the following steps: firstly setting motor vehicle collision parameters and inputting into a well-established computer simulation system which automatically calculates the motor vehicle collision parameters for further judgment and analysis; calculating stress condition, so as to judge whether elastic-plastic collision or rigid collision occurs; then calculating collision energy so as to activate a sound trigger to generate collision sound, and closing the motor vehicle braking or collision sound; and finally, recording the collision cache data, outputting and displaying collision energy files, screenshot files and parameter files, and terminating the collision process. The method provided by the invention has the advantages of simple technological process, reliable design principle, and real simulation scene, is favorable for analysis and judgment, and can be widely used for teaching, scientific research, accident analysis and other occasions.

Description

Technical field: [0001] The invention belongs to the technical field of motor vehicle collision accident simulation, and relates to a process for simulating a motor vehicle collision accident during driving in a computer system, in particular to a method for simulating a motor vehicle collision accident. Background technique: [0002] In the existing demonstrative forms of analyzing motor vehicle accidents, there is no realistic report on the results of simulating the scene of motor vehicle collision accidents. The simulation form of motor vehicle collision scene is for analysts with different needs to judge the situation of motor vehicle collision scene in different situations. For example, accident appraisers can use this method to analyze and judge the situation of traffic accident scene and make judgments on accident responsibility; teachers in the teaching process This kind of simulation technology is often needed in the school to explain the principle of collision, the...
