Finite element method for reconstruction of road traffic accidents

摘要

The article examines the accident rate statistics on the roads of the Russian Federation, analysis of which provides the basis for posing the issue of improving the quality of expert study of road traffic accidents. The theory of the finite element method is studied and an algorithm for simulating road traffic accidents is proposed, which is based on the analysis of deformation damage to a vehicle and calculation by finite element method. The proposed algorithm is used to calculate the vehicle speed during frontal impact with an undeformable obstacle. The result is verified by calculating the fraction of kinetic energy expenditure (ΔЕ) for development of deformations and the speed equivalent to this expenditure by “Crash3” algorithm. The analysis of the obtained data showed high efficiency of the algorithm proposed by the authors.
