摘要
基于ABAQUS-FLUENT软件开展柔性充气翼流固耦合分析,采用反距离加权平均法实现耦合界面气动压力分布传递,采用常体积转换法实现变形数据传递,分析获得了充气翼翼面刚度和屈曲特性与翼面内外压差的关系;建立了充气翼模拟加载试验系统验证了分析方法的可行性.结果表明,流固耦合方法用于充气翼变形分析是可行的,分析结果与模拟试验结果能够较好地吻合.
ABAQUSFLUENT FSI software. Distanceweighted average interpolation function was used to transfer aerody namic pressure distribution between coupling interfaces. Deformation data was transferred using constant vol ume tetrahedron transformation method. Relationship among interior pressure, stiffness and buckling behavior of inflatable wing was obtained. Analog loading system of inflatable wing was established to validate the feasi ble of the optimization scheme. The results show that FSI method is applicable to make the deformation analy sis of inflatable wing. The results of the FSI analysis and the analog loading test coincide to each other well.
