Abstract: Free vibration variational equation of a camped pipe
conveying fluid (liquid-solid coupled problem) is derived, based on
variational principle. The natural frequency formula of a camped pipe
conveying fluid are obtained by used of direct method. The influence of
flowing velocity on natural frequency of a camped pipe conveying fluid
is discussed. The limit velocity of liquid in the camped pipe conveying
fluid is obtained.
Key words: Variational principle Liquid-solid coupled problem
Direct method camped pipe conveying fluid Limit velocity of
