Abstract

A ten-degree-of-freedom digital computer model for finite disturbances of an automobile has been modified to include a full compliment of aerodynamics forces and moments. The computer model provides for the input of a general aerodynamic (wind gust) disturbance. This simulation is used to study the response of an automobile to a cross-wind disturbance. The response of a fixed-control vehicle to a gust is found to be potentially hazardous for high vehicle speeds. An automatic guidance system is added to the model and the effectiveness of the guidance system in reducing cross-wind response is demonstrated. The response of both a fixed-control and a steered vehicle to a gust representative of the wind-blast from a passing vehicle is also analyzed.
