摘要: 厢式货车超车过程的气动特性对于行驶稳定性与安全性非常重要,本文研究采用实验和数值模拟计算相结合的方法对厢式货车的超车过程进行研究,通过烟风洞实验获得厢式货车超车过程的外流场分布特性,建立厢式货车的计算模型,通过数值模拟计算获得厢式货车超过过程的阻力、侧向力分布特性。本项目研究可以为厢式货车运输安全研究提供一定的理论依据。
Abstract: Aerodynamic characteristics of overtaking process of van truck are very important for driving stability and safety. In this paper, the overtaking process of van truck is studied by combining experimental and numerical simulation methods. The distribution characteristics of external flow field of overtaking process of van truck are obtained through smoke tunnel experiments, and the calculation model of van truck is established. Through numerical simulation calculation, the overtaking process of van truck is studied. Distribution characteristics of resistance and lateral force of van truck in overtaking process are obtained. The research of this project can provide a theoretical basis for the safety research of van truck transportation.
