Abstract

Objective of this study is to perform a design analysis for an excessive vibration problem of a piping structure due to mechanically induced resonance. But in most process piping design activities the dynamic vibration analysis of the piping system are not of much interest compared to static analysis. However if process plants come across such problem during their operation then they need to be addressed as critical and should be analyzed in detail. These vibrations are basically induced by the rotating or reciprocating equipment like compressor, pump, turbo machine etc. attached to the piping system. They can be easily detected & monitored by modern condition monitoring facilities. However for rectification, detailed review of piping design for both static and dynamic aspects are absolutely necessary. Modern computerized design and analysis tools are very much helpful in these cases. In this paper the approach involves both practical evaluation and computer simulation. The practical vibration analysis is done with analyzing actual vibration reading of the piping structure and plotting the operating deflection shape (ODS) using the software. Computer simulation is done for static design review and modal analysis to evaluate natural frequency and mode shapes using piping stress analysis software CAESAR II. This activity also involves the finite element analysis (FEA) technique. Results are compared to verify the cause of resonance and also to find the solution on resonance problem.
