The forces and moments experienced by certain passenger cars are measured as a function of time as the vehicles are disturbed aerodynamically by passing buses and trucks in the influence of sidewinds. Measurements were made on 1/10 scale models moving at actual speeds of up to 70 mph. The situations studied include passing encounters in which automobiles pass and are passed by the disturbing bus or truck traveling in the same direction as well as opposite directions. The parameters included vehicle lateral separation, vehicle speeds, and relative direction and side-wind velocity. Results have direct implications on vehicle safety for the situations studied.
