本文从非线性有限元的一般方法出发，结合应用加权残数技术和ALE边界元法，对Chater梁的屈曲传播进行了完全的动态分析，抛弃了前人一直采用的准静态和动稳态假设；另外，基于势流理论和非线性液面条件，还考虑了结构充液后由于流固耦合作用对屈曲传播所造成的影响，大量算例揭示了结构的菲线性、作用载荷、屈曲传播速度以及液体介质之间的内在关系，从而对屈曲传播有了更深入的认识。
It was found that the RNG model was better than standard model owing to introducing the source item of flow field distortion effect by factor C1*. The Tet/Hybrid grid elements were divided by Tgrid method. The computation could be converged easily and the results could be more accurate with higher density grid, but it might take more time. The maturation tank was divided to a rotatory zone and stationary zone by multiple reference system method, and the Eulerian model was used as stable state computation for the continuous media interpenetrated each other instead of momentary state computation which took more time.
