Combined accident simulation and reconstruction system of vehicle bumping two-wheeled or three-wheeled vehicle and then bumping fixture

Abstract

The invention discloses a combined accident simulation and reconstruction system of vehicle bumping two-wheeled or three-wheeled vehicle and then bumping fixture, which is used for police traffic administration management to identify road traffic accidents. The running vehicle speed and bumping vehicle speed of the vehicle in the combined accident in which the vehicle bumps two-wheeled or three-wheeled vehicle and then bumps fixture are calculated by using the basic data obtained from the reconnaissance of accident scene so as to realize the two-dimensional orbit description, the three-dimensional process reconstruction of the vehicle, the main calculated datasheet output of the combined accident in which the vehicle bumps two-wheeled or three-wheeled vehicle and then bumps fixture, and the brief description textual output of the accident process. The system efficiently improves the technical content of traffic accident identification and processing so that traffic administration department, accident identification unit and accident parties highly agree on the analyzed identification result, thereby achieving the important functions of distinguishing responsibility, avoiding aggravating contradictions, reducing social unstable factors, increasing the harmonious development of social life, and the like; simultaneously, the system can be widely applied for popularization, and has obvious industrial generality and social public welfare.

Description

technical field [0001] The invention relates to the technical field of computer simulation applications, in particular to a computer analysis calculation and simulation reproduction simulation system for a type of combined accident when a car collides with a two-wheeled or tricycle and then collides with a fixed object. Background technique [0002] A car hits a two-wheeled or tricycle and then hits a fixed object combination accident refers to a special type of road traffic accident accident that occurs after the car collides with a two-wheeled or tricycle and then the car collides with a fixed object on the ground. The movement state of the car after a collision accident is out of control, and a secondary accident occurs in which it collides with a fixed object on the ground, so that the movement of the car after the collision with a two-wheeled or tricycle is no longer a complete vehicle-ground mechanics However, after the accident car rushes out of the lane, there is ano...

Problems solved by technology

[0003] After searching the existing technical literature, it is found that the patent application number is 200810038173.7, and the name is the car and two-wheeler collision accident reproduction system. This technology provides a car and two-wheeler collision accident reproduction system, including information collection, process simulation, optimization Reproduction and result processing, using the multi-rigid body method to establish a collision model between a car and a two-wheeler, mainly for traffic accidents of the type of car collision with a two-wheeler, the accident scene data acquisition module uses three-coordinate calibration objects and circular shooting methods On-site information, using virtual reality technology to establish a three-dimensional model of the accident scene, according to the motorcycle occupant's human injury inspection report, combined with the main model of the multi-rigid body dummy to form a new combined dummy model, using the multi-rigid body collision theory for simulation calculations, simulating the car The whole process of collision with a two-wheeled vehicle cannot be applied to complex combined accidents such as a car colliding with a two-wheeled or tricycle and then colliding with a fixed object
