The Study on the Influence of Gust Wind on Vehicle Stability
2014
In this paper, the vehicle driving characteristics are investigated under different Force level of gust wind based on the CFD theory. The distributed pressure acted on the vehicle side surface is equivalent to the six-component force on vehicle gravity center. The six-component force are explored and compared in different Force level of gust wind. The results show that the lateral force Fy and yaw moment Mz vary with v shape and shape under gust wind, respectively. The slopes of the result curves increase with greater Force level of gust wind. Gust wind gives most influence on Fy and Mz while has little effect on other component force. The work will provide a methodology for vehicle stability research under gust wind.
