Component-based TPA is a significant part of the VIBES Methodology. Over the past years, VIBES further developed the component-based TPA methodologies and worked together with clients to tackle all types of sound & vibration issues based on measurements.
With the variety of TPA methods growing over the past years, the need for a clear classification of methods and their pros and cons became inevitable. In 2015, VIBES’ own Dr. Maarten van der Seijs and Dr. Dennis de Klerk, together with Prof. Dr. Daniel Rixen, proposed a general framework to structure the different TPA methods.
For the first time, similarities between well-known classical methods (such as mount-stiffness and matrix inversion) and the popular Operational TPA method have been made clear. More importantly, all recent approaches dealing with “Blocked Forces” were included and categorized into the component-based TPA family, in a way that helps the engineer choose the right approach, test bench design or source description for the case at hand.
