System for reproducing collision accident of vehicle and two-wheel cycle

Abstract

The invention relates to a collision case playback system of the cars and two-wheeler in the computer application technical field, wherein an accident site reconstitution module collects the accident field data and picture, reconstitutes and reverts the site; a two-wheeler driver modularization dummy customizing module builds a dummy model matching with the body shape of the driver, extracts the damaged sensitive parts of the dummy model, sets up a finite element model, becomes a new conbination dummy model combined with the multi-rigid body dummy main body model; a collision process emulating module performs the scaling of model matching with the sufferer bodily form characteristics, meanwhile builds the integral accident site three-dimensional model before the accident, and simulates and computes the primary collision result; an optimization recurrence module builds the optimization flow, optimizes the collision simulation; an accident recurrence result post-processing module displays the optimized simulation result in the collision process animation and the collision parameters. The invention can realizes the site information collection, fast simulation and modelization, short treating period, high precision and high reliability.

Description

technical field [0001] The invention relates to a system in the field of computer application technology, in particular to a system for reproducing collision accidents between automobiles and two-wheeled vehicles. Background technique [0002] Two-wheeler drivers are the most vulnerable group in traffic accidents. Severe impact injuries can lead to death, especially in China, which has the largest number of motorcycles and bicycles in the world. Regardless of the number of accidents or the number of deaths and injuries in all types of vehicles account for a very high proportion of traffic accidents. National statistics in recent years show that among the traffic accident deaths, motorcycle drivers account for 21-26% of the total traffic accident deaths, and cyclists account for 11-12% of the total traffic accident deaths. Accident process reproduction is an important research topic, and automobile and two-wheeler collision accident reproduction is an important content in th...

[0005] After searching the existing technical literature, it is found that the patent application number is 200610029123.3, and the name is "A Reproduction Optimization Method for Car-Person Collision Accident Based on 3D Multi-Rigid Body Model". This technology provides a method for reproducing car-person collision accident, including model establishment and simulation optimization, which mainly proposes a theoretical algorithm for car and pedestrian traffic accidents, which cannot be applied to the field of car and two-wheeler collisions, and there are still great defects in the application of accident reproduction in actual cases, such as the inability to carry out accident scene information Acquisition, optimized reproduction, and result processing, etc., and the proposed model does not have Chinese human characteristics, and the optimization algorithm is not complete
