| 摘 要： | 本文探讨一种结构-内流体组合单元,沿流体两个正交方向取用解析函数族,将结构与内流体耦联振动的三维问题化为一维问题求解,致使计算工作量大为减少.为适合各种不同类型问题,文中建立了柱形与钳形组合单元,给出了算例,讨论了方法的精度.

| Abstract: | A composite structure-internal liquid element is proposed in this paper. Through the use of analytical functions in two orthogonal directions. the three-dimensional problem of coupled structure-internal liquid vibration is reduced to a one-dimensional one, resulting in a drastic reduction in computing efforts.Cylindrical and conical frusium composite elemenls are proposed lo suit different problems, and examples are presenled to demonsirate the accuraey of the method. |
