| 摘 要： | 基于自研软件平台UNSMB,采用CFD/CSD耦合的颤振时域分析方法,对某带舵面垂尾的风洞模型进行了跨声速颤振特性分析。研究了洞壁对颤振边界的影响,通过改变网格大小,设置不同的边界条件,对洞壁的模拟方法进行了对比研究,最终获得了与试验数据吻合很好的结果,表明洞壁对模型的颤振边界存在较大影响,同时表明UNSMB平台的跨声速颤振计算具有较高的精度。

| Abstract: | Based on UNSMB platform of ARI ,the transonic flutter boundaries of a vertical tail model with rudder were calculated by coupling CFD/CSD.The wind tunnel wall influence was studied by setting dif-ferent boundary conditions and CFD grid .The numerical results agreed well with the test ,which indicated that the flutter characteristics of the model was greatly impacted by wind tunnel wall , and UNSMB had well accuracy on transonic flutter calculation . |
