Automobile oblique collision accident analytic computation and simulative reappearance computer system

Abstract

The invention discloses an automobile oblique collision accident analytic computation and simulative reappearance computer system for road traffic accident assessment of the public security traffic administrative department, which can use basic data obtained by investigating the accident scene to compute driving speed and collision speed of the automobiles in the automobile oblique collision accident, and realize the two-dimension track description, the third-dimension process reappearance, the output of a main computation data table of the automobile oblique collision accident and the output of an accident occurrence process brief text of the accident automobiles. The invention is suitable for being extensively popularized for effectively improving the technological content of traffic accident assessment and treatment so that the analysis assessment result is easy to be highly recognized by the traffic administrative department, the accident assessment authority and the accident parties; the system plays an important role in distinguishing responsibility, avoiding aggravating contradiction, reducing social unstable factor, enhancing harmonious operation of the social life and the like so as to promote the development of the assessment of road traffic accident in our country in a more scientific, accurate and authoritative direction.

Description

technical field [0001] The invention relates to the technical field of computer simulation application, in particular to a computer analysis calculation and simulation reproduction simulation system of vehicle oblique collision accident form. Background technique [0002] Vehicle oblique collision accidents account for a large proportion of traffic accidents, seriously threatening the safety of drivers and passengers. According to the statistics of my country's traffic management department, among all road traffic accident forms, vehicle-to-vehicle oblique collision accidents are always Accounted for more than 80% of the total number of accidents. The analysis and identification of traditional automobile oblique collision accidents is mainly based on the statements of the parties involved in the accident scene and eyewitnesses, and the final stop position of the accident vehicle, road structure, vehicle braking marks and other accident scene data obtained from the road traffi...

AI Technical Summary

Problems solved by technology

At present, domestic and foreign studies on the calculation and simulation of vehicle oblique collision accidents are mostly based on finite element analysis models. It is difficult to realize real-time simulation of the collision process due to the grid generation process that takes hours or even days. The mechanical parameters of different models are also different, so the application in traffic accident simulation is still at the theoretical stage

Foreign accident simulation software such as PC-CRASH requires the user to determine the friction coefficient, rebound coefficient and other parameters of the collision process, and then modify the initial value, friction coefficient, rebound coefficient, collision center position, contact surface angle and other parameters to simulate the entire process of the accident , and the input data of PC-CRASH is various, most of which are vehicle professional technical parameters, which are not universally applicable
