| Abstract | The problem of critical velocity of fluid-conveying pipes resting on a Winkler foundation with elastically supported of the pipe is studied in this paper. The aim of this work is deriving a new analytical model to perform a general study to investigate the dynamic behavior of a pipe under general boundary conditions by considering the supports as compliant material with linear and rotational springs, and study the effect of foundation and stiffness values on the critical velocity. This model describes both the classical (simply support, free, built, guide) and the restrained boundary condition and it is not required to derive a new critical velocity equation if the boundary conditions is changed ,also the result will be near to reality by knowing the physical parameters for the compliant material and the pipe. The cases studied in this work are flexible support of the ends pipe with or without intermediate restrain support, and pipe resting on Winkler foundation. . The general theoretical conclusions are that the supports and foundation values have significant effects on the dynamic characteristics of the pipe. Keywords— Pipe conveying fluid, Critical velocity, Elastic support, Winkler foundation. |
