摘要
本论文通过对典型钝体断面模型颤振和固定时以及加稳定板模型颤振时进行表面压力分布测试。首先分析典型钝体断面模型颤振时表面各部分压力波动特性,然后运用本征正交分解(POD)方法分析典型钝体断面模型颤振时表面压力分布特性,最后将原断面模型颤振时压力分布和固定时压力分布进行对比分析。
Typical bluff-section model pressure distributions are measured in the condition of fixed model as well as fluttering model with and without stabilizer in this paper. Firstly, surface pressure fluctuation characteristics of the bluff-section model during flutter are analyzed. Then, surface pressure distribution characteristics are analyzed based on proper orthogonal decomposition （POD）. In the end, pressure distributions are compared between fixed model and fluttering model.
