• Modal Analysis To find the natural frequencies and mode shapes of the pipe, you need to perform a modal analysis. Various elastic piping components such as pipes, bends, tees, flanges etc. they are part of a piping system and also the piping system has non-uniform mass distribution due to size variations, different fittings and other various rigid components. Therefore, once the system is displaced from static equilibrium, its components begin to oscillate with different mode shapes and begin to vibrate at the associated frequencies. It is critical to find the natural frequency of the piping system to determine the dynamic load factors (DLF) and also to determine the pipe support span to avoid harmful vibrations. You must perform the modal analysis before the other dynamic analysis because these use the natural frequencies of the system obtained from the modal analysis. When a piping system is adequately supported to standards, the lowest natural frequency shall not be less than 4 or 5 Hz.• Harmonic
