基于虚拟现实的汽车高速路侧风稳定性试验虚拟场景建模及试验研究

Virtual Scene Modeling and Experimental Study of Automobile Expressway Crosswind Stability Based on Virtual Reality

基于虚拟现实技术,三维构建了高速道路场景的主要场景模型,包括地面模型、附属景物模型、高速路隧道模型、汽车模型等,并对模型进行优化处理,从而构建汽车高速路侧风稳定性虚拟试验场景,为汽车高速路侧风稳定性试验提供理论和方法依据。完成了汽车高速路侧风稳定性实车道路试验,重点研究了高速隧道口侧风对汽车行驶轨迹的影响。实验证明隧道进出口的侧风对汽车的行驶轨迹有一定的影响,尤其在隧道出口汽车行驶方向偏离显著,达到了研究预期。

The main 3 D model,including ground model,scene model affiliated,expressway model,tunnel model and vehicle model,were built and optimized based on virtual reality,hence the theoretical and method basis of road test of automobile high speed cross-wind stability were provided.Further more,the expressway test of automobile cross-wind stability was completed,and the effect of the cross-wind at the tunnel on keeping running track was mainly researched.The road test show that the cross-wind has a significant effect on the running track as expected,especially at the tunnel exit.
