Most equipment vibration problems are due to mechanical, acoustic, or flow related excitation – and if left unchecked, will cause equipment failure, which may lead to greater repair costs. Components vibrate at particular natural frequencies – these frequencies and resulting mode shapes can be determined using vibration and modal analysis. Often, simple analysis can be performed, while for more complex systems, finite element analysis is performed to determine to determine the dynamic response.
A few examples include:
A vibrating component or system often leads to fatigue – which eventually causes equipment malfunction, or catastrophic damage. Fatigue cracks usually initiate at the surface, and for this reason, the condition of the surface and the environment are important factors influencing fatigue behavior.
Our engineers are experienced in vibration, materials and fatigue analysis. Tom O’Donnell has performed vibration and fatigue analysis on numerous components, and Bill O’Donnell Sr. has not only served as the Chairman of the Subgroup of Fatigue Strength of the ASME Boiler and Pressure Vessel Code – but has also performed fatigue analysis on many systems.
