Abstract

Abstract:

The transfer matrices of the axial, flexible and torsional modes of fluidconveying elbow pipe are deduced considering fluidstructure interaction between pipe and fluid. Calculate the modal frequency and shape of a “U” shape pipe with Transfer Matrix Method and ANSYS software respectively. The results indicate that Transfer Matrix Method is an effective way to analyze fluidconveying pipe. The effect of fluidstructure interaction can not be ignored which will depress the modal frequency of the pipe.

Key words: vibration and wave, fluidconveying pipe, transfer matrix, modal analysis, fluidstructure interaction

摘要：

考虑流固耦合作用，建立同时考虑轴向、横向、扭转振动的充液弯管传递矩阵。对一“U”形充液管道进行研究，分别使用传递矩阵法和ANSYS软件计算模态频率和振型。结果说明，传递矩阵法可以有效的对充液弯管进行模态分析，且流固耦合作用会降低管系固有频率，影响不可忽略。
