The Effect of the Crosswinds on the Stability of the Moving Vehicles

摘要

The article describes the effect of the crosswinds on the moving heavy road vehicles. It gives the mathematical descriptions of two extreme situations originated from the crosswinds - side deflection from the directness and the rollover of the vehicles. It also analyzes factors affecting the action of the wind on the vehicle, as a tire cornering stiffness, instantaneous vehicle weight, axle load, the position of the gravity center of the vehicle. Both situations present a greater risk for empty vehicles with tarpaulin superstructure, and therefore some types of them are addressed in the article.
