Embodiment 1

[0095] At about 19:30 on August 16, 2010, on the south side of the intersection of Xifeng Road and Yanhuan Middle Road in Xi'an, a Shaanxi Automobile brand heavy-duty dump truck traveling from south to north and a truck traveling from south to north Dayang brand DY110ZK three-wheeled motorcycle had a collision accident. The accident site is a highway road with two-way two-lane lanes in the north-south direction, and the total width of the road surface is 9m. The accident happened on a sunny day with dry asphalt.

[0096] Simulation calculation results: the speed of Shaanxi Automobile brand heavy-duty dump truck is 44.8km / h when the driver brakes, and the calculated collision speed is 42.7km / h.

[0097] Operation steps of the data input dialog window:

[0098] ① if Figure 9 As shown, run the system, execute the [car collision two-wheeled or tricycle accident] command, and pop up the dialog box [dialogue window of the basic situation when the accident occurs]. According to ...

Abstract

The invention discloses a system for simulating and reproducing a collision accident between an automobile and a two-wheel or three-wheel vehicle, which is used for assessing a road traffic accident by the traffic control department of the public security organ. Through the system, basic data can be obtained by inspection of an accident scene, the traveling speeds and collision speeds of the automobile and a motorcycle in the collision accident between the automobile and the two-wheel or three-wheel vehicle are obtained by calculating, and two-dimensional track description and three-dimensional process reproduction of accident vehicles, output of a major calculated data table for the collision accident between the automobile and the two-wheel or three-wheel vehicle and brief description text output of an accident occurrence process are realized. The system can be popularized and applied widely, effectively increases the technical content of assessment and treatment of the traffic accident, achieves an analysis and identification result which is easily and highly approved by the traffic management department, the accident assessment unit and parties of the traffic accident and plays important roles in distinguishing responsibilities, avoiding conflicts, reducing social unstable factors, improving harmonious operation of social life and the like.

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 collision accident forms between automobiles and two-wheeled or tricycles. Background technique [0002] Collision accidents between automobiles and two-wheeled or tricycles refer to a common form of road traffic accidents involving frontal (or side, rear-end) collisions between automobiles and two-wheeled or tricycles (including motorcycles, bicycles, electric bicycles, and tricycles). The motion state of a two-wheeled or tricycle after a collision accident is out of control, and parabolic motion in the air or ground slip motion occurs again, resulting in the complexity of the calculation and analysis of vehicle motion mechanics and the simulation and reproduction of the accident process in such accidents. It is one of the difficulties and cutting-edge technologies in the fie...
