随着斜拉桥跨度的持续增长,结构更趋于轻柔,风作用下的结构稳定性已成为超千米主跨斜拉桥设计和研究的重要问题。采用大跨度桥梁三维非线性空气静力和动力稳定性分析方法,对1400m主跨的超大跨度斜拉桥进行了空气静力和动力稳定性分析,并与同等主跨的悬索桥进行对比,从抗风性能角度探讨了斜拉桥在超千米主跨桥梁中的适用性。在此基础上,分别就主梁的高度和宽度、桥塔结构型式、桥塔高跨比、边主跨比、辅助墩设置、斜拉索锚固方式等结构设计参数对超大跨度斜拉桥空气静力和动力稳定性的影响进行了分析,指出了关键的设计参数及其合理取值。结果表明:与同等主跨的悬索桥相比,斜拉桥的结构刚度更大,空气静力和动力稳定性更好,适宜采用于超千米主跨的大跨度桥梁;超大跨度斜拉桥在增大主梁高度、减小梁宽、采用倒Y形桥塔并增大塔高、减小边跨长度、边跨设置辅助墩以及部分斜拉索地锚等情况下,都可以获得比较好的空气静力和动力稳定性。

This article summarizes our studies on micro flow sensors fabricated on a flexible polyimide circuit board by a low-cost hybrid process of thin-film deposition and circuit printing. The micro flow sensor has merits of flexibility, structural simplicity, easy integrability with circuits, and good sensing performance. The sensor, which adheres to an object surface, can detect the surface flow around the object. In our study, we install the fabricated micro flow sensors on micro aerial vehicles (MAVs) to detect the surface flow variation around the aircraft wing and deduce the aerodynamic parameters of the MAVs in flight. Wind tunnel experiments using the sensors integrated with the MAVs are also conducted.
