某型商务车风阻的分析及优化

Analysis and Optimizatio n of A Business Car Wind Drag

本文通过对某典型商务用车进行CFD仿真,确定了影响风阻的关键因素,对其进行优化并重新计算,计算结果表明经优化后汽车风阻明显变小,优化效果明显,对汽车的降风阻设计有一定的指导作用。

Through the CFD analysis on wind drag of a typical business purpose vehicle, this paper found the main part of the larger influence on wind drag, optimized and calculated again. The results show that the wind drag of the business purpose vehicle significantly smaller after optimized. The effeet of optimization is obvious and the results can provide some guidance for reducing wind resistance design.
