摘要
Abstract
The differential equation of fluid-conveying pipes considering distributed follower force and elastic foundation is established. The equation is discreted and solved by Galer-kin method and the frequency characteristic values are solved by bending moment transfer method . The effects of crack location and elastic foundation stiffness to the form of instabili-ty of the pipes under the distributed follower force are analyzed. Results show that the elas-tic foundation stiffness can enforce the stability of the pipes effectively,and the effects are more obvious when the crack location is closer to the middle of the pipe.关键词
