Investigation Of Automobile Wheel Impact On The Road Border

Impact of motor vehicle wheels on the road border, as a result of which the wheel tire gets dismantled, is considered in this paper. The required force and minimal speed of driving, which is equivalent to the expenditures of the kinetic energy, necessary for dismantling the tire from the wheel rim after impact on the road border, are determined. The values of this force and speed, typical of the motor vehicles, attributed to different classes, their dependence upon the height of the road border, and the angle of impact with the border are fixed. More precise methods for calculating automobile speed prior to a traffic accident are suggested, by taking into consideration the expenditure of the kinetic energy necessary for dismantling the wheel after occurrence of its impact on the road border.
