| description | Piping system is the main structure in many industrial applications, especially for large industry
relating with processing and transporting fluids, such as oil and gas industries. The fluid-induced
vibration is often the cause of structural fatigue in pipes and therefore piping vibration need to be
closely monitored. In case of high piping vibration, knowledge of the natural frequency of a pipe
section is crucial for an engineer to propose the right troubleshoot action, either for a temporary
or even for a long-term solution for the piping vibration. Therefore, prediction of the pipe natural
frequency using a simple formulae is thus of interest, without dealing with complex numerical
simulation using a commercial software which consumes cost and time. In this paper, the vibration mode shapes of various possible geometries of pipes in practice were simulated in ANSYS
and the simulated natural frequency is related to a natural frequency of an Euler-Bernoulli beam
using a correction factor for each corresponding piping geometry. This paper extends the previous
work by allowing the boundary conditions of the pipe ends to be simply supported, in addition to
the clamped edges. In this way, the frequency factor charts are presented in the range of possible
correction factor values to accommodate the real conditions of pipe arrangement in practical
application. An experiment from a case study to verify the proposed method is also presented. |
