The application of simulation of car wheel interation with the road elements to road accident examinations

Abstract

Collision of the automobile wheels with the vertical obstacle, as a result of which the wheel tire gets dismantled, is considered in the present article. The required force and the minimal speed of driving, which is equivalent to the expenditures of the kinetic energy, necessary for dismantling of the tire from the wheel rim after collision with the obstacle, are ascertained. The values of this force and speed, typical of the automobiles, attributed to different classes, their dependence upon the height of the obstacle and the angle of collision with the obstacle are fixed. The more precise methods for calculation of the automobile speed prior to the traffic accident, by taking into consideration the expenditures of the kinetic energy, necessary for dismantling of the wheel after occurrence of its collision with the vertical obstacle, is suggested.
