SELECTED PROBLEMS IN A VEHICLE-TO-TRUCK COLLISION MODELING

Abstract

A selected case of a frontal, eccentric and oblique road vehicle-to-truck collision has been analyzed here as an example of the potential resultant motion by the motor vehicle with the truck performing a planar motion. This case is a pure problem of collision mechanics, so the main aim of the case presented here was to identify the selected parameters of such a collision with the three components of the collision impulse of only one vehicle taking part in it. The problem was analyzed with the use of a computer simulation performed in a software called V-SIM which is quite popular as a tool for accident reconstruction by e.g., forensic experts and others associated with road safety, especially in Poland. The results of all simulations were important in providing the basics of mathematical modeling regarding collision mechanics. The obtained observations may further be used for a dedicated software, should such be created. Not only a normal and a tangential but also a bi-normal direction versus the adopted plane of collision was considered.
