Vibration Analysis of Liquid-filled Pipes with Fixed-hinged Under Fluid Structure Interaction
摘要
Abstract
In this paper,the control equations of fluid structure interaction vibration of liquid-filled pipes with fixed-hinged were established on the basis of Hamilton's vibration principle.The formulas of the natural frequency of the pipe,critical pressure and critical velocity of the liquid were obtained by means of direct method.The fluid structure interaction vibration of pipe of Christmas tree was calculated by this method,the influence of velocity and pressure of the liquid on the natural frequency of the pipe were analysed.And the curves of natural frequency,critical pressure and critical velocity with the length of the pipe,the pressure and velocity of the liquid are acquired.关键词
