Problems solved by technology
This type of calculation method is too simplistic and idealized, and it is impossible to reproduce the accident process. Using this method to identify the vehicle speed and motion state of the crash accident cannot adapt to the complex scene of the crash accident, and it has great advantages in use. Limitations, accident analysis and appraisal results have poor precision and low reliability
[0005] After searching the existing technical literature, it is found that the research on the calculation and simulation of crash road traffic accidents at home and abroad has not yet been carried out.

Embodiment 1
[0075] At 13:25 on September 13, 2008, at 525 kilometers + 300 meters on Sichuan Provincial Highway 101, a bus traveling from Nanjiang County to Guangwushan Township crashed. The accident scene is a sharp curve section. When the accident happened, the weather was clear and the concrete road was dry. Simulation calculation results: the speed of the car at the moment of falling off the cliff is 17.8km / h, the speed when the driver takes braking measures is 55.1km / h, and the speed when the car hits the guardrail is 22.8km / h.
[0076] Operation steps of the data input dialog window:
[0077] ① participate Figure 8 , run the software, execute the [Automobile Highway Crash Accident] command, and the [Dialogue Window of Basic Situation of the Accident Occurrence] dialog box will pop up. According to the basic information data of the accident obtained by the traffic police on the accident scene inspection, the basic information at the time of the accident is input in each text box ...

The invention discloses a computer system for analysis, computation, simulation and reconstruction of a car falling accident, which comprises six analog computation subsystems, namely a subsystem for recording and storing basic data of the car falling accident site, a subsystem for calculating the motion quantity of a car at the moment of falling, a subsystem for calculating the motion quantity of the car at the moment that the car crashes with vehicle-road protecting facilities, a subsystem for calculating the drive speed of the car undergoing the falling accident, a subsystem for reconstructing process of car falling accident in a three-dimensional mode, and a subsystem for outputting and describing an analog computation result of the car falling accident. The inspection data of the site of the car falling accident are input through an operation interface of the computer system, and are normalized and checked by the system; afterwards, relative calculation, reconstruction and outputmodules are started to accomplish the analysis and the calculation of the sports mechanics status of the car undergoing the car falling accident, and the three-dimensional reconstruction of the process of the car falling accident, thereby realizing the functions of recording and storing the inspection data of the site of the car falling accident, and outputting a computational data table about characteristics of the car falling accident.
Description
technical field [0001] The invention relates to the technical field of computer simulation application, in particular to a car crash analysis, calculation and simulation reproduction system. Background technique [0002] Car crashes are the main form of serious road traffic accidents. From 2007 to 2009, there were 76 serious road traffic accidents in my country that killed more than 10 people, of which 45 accidents occurred due to car crashes, accounting for 59.2% of the total number of accidents. Car crashes not only bring huge losses to people's lives and production, but also increase the pressure and workload of the public security traffic management department to deal with traffic accidents. Due to the extremely complex motion state of the vehicle during the crash, it poses a challenge to the traditional analysis methods and means of road traffic accidents in my country, and also poses serious challenges to the scientificity and rigor of the public security traffic manag...
