Free Vibration Characteristics of Elastically Supported Pipe Conveying Fluid
Keywords:
Pipe conveying fluid, Natural frequency, Critical velocity, and Elastic supportAbstract
In this study, the effect of support values on
the natural frequency and critical flow velocity
of a straight pipe conveying laminar flowing
fluid is studied. 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. 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 frequency
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.
