| 摘 要： | 采用二维不可压缩无粘流体模型，探讨了板状结构的流致振动问题。发现板在两端简支、中点联结松动时，结构首先出现屈曲失稳，而不会发生颤振失稳。求得了具体结构参数情况下的第一阶屈曲临界流速，计算了结构参数变化对临界流速的影响。

| Abstract: | Adopting two_dimensional incompressible,inviscid fluid model,some problems of flow_induced vibration are investigated.For pined_pined,loosed midpoint support plate,it is found that the plate's buckling instability will happen first while the flutter instability will disappear.The first_order critical fluid speed with concrete structural parameters is calculated,and the influence on critical fluid speed is studied when the structural parameters are changed. |

| Keywords: | plate-type structure flow-induced vibration buckling instability flutter instability critical fluid speed |
