| 摘 要： | 依托开口式整车风洞,以阶背式MIRA(Motor Industry Research Association)模型为实验对象,通过雷诺数扫掠测试,确定了力/压分测和力/压同测时气动力数据误差的变化规律;基于偏航工况下气动力的测试数据,明确了力/压分测和力/压同测时气动力数据误差的分布规律.依据计算流体力学的仿真结果,从流动机理层面剖析了误差产生的原因.最后,对力/压同测法在风洞实验中的具体实施及适用范围进行了总结.

| Abstract: | In full scale automotive wind tunnel with open jet test section, targeting notchback MIRA body, variation law and distribution rule of force/pressure test data error between simultaneously testing method and respectively testing method were revealed by wind tunnel test in a range of Reynolds number and yaw angle. The error was subsequently explained by computational fluid dynamics in view of flow mechanism. Finally, the specific implementation and application scope of force/pressure simultaneously testing method in full scale automotive wind tunnel were concluded. |
