A simple static analysis of moving road vehicle under crosswind

• A static model for the determination of critical wind speed for overturn, sideslip and rotation is considered.
• Explicit formulas for critical wind speed for all three possible wind induced accidents are derived.
• Numerical examples are given and compared to field observations.

This article is devoted to vehicle safety in the crosswinds. A static model to determine the critical wind speed for overturn-, sideslip- and rotation-type of accidents is considered. The basic equations were defined by assuming that the vehicle moves in a uniform straight line. Explicit formulas for the critical wind speed for all three possible wind-induced accidents are derived to provide the new critical wind speed formulas for rollover and rotation wind-induced accidents. Numerical examples are given and compared to field observations.
