汽车侧风稳定性动态耦合方法研究
Research on Vehicle Stability under Crosswind Conditions by Dynamic Coupling Method
摘要
Abstract
For the study of vehicle stability under crosswind conditions,through the analyses of computational fluid dynamics(CFD)software FLUENT dynamic meshes and UDF,a dynamic cou-pling method was proposed combined with two-way coupling communication technology.The aerody-namics with vehicle dynamics was coupled.And the simulation results of dynamic coupling were com-pared with that of traditional static coupling.The influences of different wind speeds on vehicle cross-wind stability were analyzed by dynamic coupling method.The calculation results indicate that vehicle stability under crosswind conditions by dynamic coupling method is worse than that by static coupling method,and the vehicle crosswind stability decreases with the increase of crosswinds.关键词
