Abstract
Stability of clamped pipes conveying fluid with distributed follower force on Paster-nak two-parameter foundation is studied. The differential equation of the pipe movement is es-tablished,and transfer matrix method is employed for solving the dimensionless equation. Based on the critical flow velocity and the variation of the complex frequency,the influences of the distributed follower force and the flow velocity on the stability of pipes conveying fluid on two-parameter foundation are analyzed for four foundation stiffness combinations. Numerical calcula-tion shows that:the stability of the system with the same foundation stiffness varies greatly for different distributed follower forces and different flow velocities;the foundation stiffness has great effects on the stability of the system with the same fluid velocity and the same distributed follower force,and the effects of the shear stiffness is greater than the linear stiffness.关键词
