Applied Of The Uncertainty Theory In Car-electric Bicycle Collisions Accident Reconstruction

With the rapid growth of the electric bicycle ownership, electric bicycle accidentincreases dramatically on the road. Car-electric bicycle collision accident is a verycomplicated process, accident reconstruction study can provide theoretical basis forthe road traffic department to provide basic data for reasonable laws and regulationsto make sure the safety of the car design. Practical significance lies in accidentresponsibility identification and insurance claims of accident reconstruction, whichrequires to improve the accuracy of the accident reconstruction.The paper through a large number of literature, analysis the accidentreconstruction collision method at present, puts forward a feasible method ofcar-electric bicycle accident reconstruction. Firstly, analyzes the characteristics ofcar-electric bicycle collision accident, sums up five kinds of the causes which lead toelectric bicycle accident and its characteristics. Besides, expounds the method tocompute the speed of general processing in car-electric bicycle accident; Research theprinciple and evaluation method of uncertainty theory completely to make clearly ofthe explicit evaluation process, and the selection of parameter conditions and usinginterval; Research on the uncertainty theory application in the traffic accident,combine the typical method of calculation speed, then given the correspondinguncertainty analysis process; To introduce the computer simulation analysis softwarePC-Crash, analysis of computer simulation of accident reconstruction feasibility, andestablish the suitable multi-rigid-body model for car-electric bicycle collisionaccident of cars, electric bicycles and cyclists; Based on the uncertainty theory of thespeed calculation method and computer simulation analysis method, which establish acomplete set of car-electric bicycle collision speed calculation to analysis thecomprehensive process.Finally, through the real car-electric bicycle collision accident case, according tothe process of comprehensive speed calculating, verify the feasibility of the methods,improve the accuracy of the car-electric bicycle accident reconstruction.
