The Mode and Nature Frequency of Pipes Conveying Fluid with Distributed Follower Force on Two-Parameter Foundation

Abstract:

The vibration differential equation of pipes conveying fluid with distributed follower force on two-parameter foundation is derived, the mode and nature frequency of clamped-clamped pipes with distributed follower force are calculated by complex modal. The relations between the nature frequency and the velocity of foundation liner stiffness and shear stiffness and mass ratio are studied. The numerical calculation shows that these parameters have a great influence to the nature frequency of the system and have certain effects to the characters vibrations of pipes.
