摘要
本文用步长样条元分析了加筋锥柱结合壳流固耦联振动特性,利用流固交界面运动耦联条件求出流场势函数与壳体位移场的关系式,利用变分原理导出振动系统运动方程,探讨了流体压力对结构振动频率的影响。
Vibration characteristic of fluid-structure interaction for joined conical-cylindrical shells with stiffeners is analyzed with the step spline elementmethod.The expressions of fluid potential and shells displacement functionare obtained by coupled motion of fluid-structure joined surface.The equa-tion of motion for a fluid-structure system is derived by making use of va-riation fundamental.The effect of fluid pressure on vibration frequency ofstructur eis discussed.
