Operational Modal Analysis of Aluminum Beams

Journal of the IEST, 2007
Natural frequencies obtained by modal analysis are important to engineers interested in predicting the dynamic behavior of structures. Traditional modal analysis involves impact testing or shaker testing, where response signal and input force are measured to obtain the transfer function. However, for large structures, input excitation force measurement

Operational Modal Analysis of a Centrifugal Compressor in Field Operation

2018
Challenging applications, such as re-injection of natural gas and carbon dioxide for the oil and gas upstream market, continue to push centrifugal compressor original equipment manufacturers (OEM) to the edge of their experience working with ultra-high density fluids.

Operational modal analysis by thermoelasticity

2009
In this work the theoretical and practical possibility of using a new measurement technique, based on high speed thermographic acquisition systems, for the study of the dynamic response of objects has been demonstrated. This methodology has been named thermoelastic modal stress analysis (TMSA).
