Mechanical Engineering Operational Modal Analysis Damping Operational Modal Analysis has received a great deal of recent research and industry interest. This method has gained popularity due to potential for reduced test time and cost as well as application to large-scale structures where traditional modal analysis is difficult or impossible. Operational modal analysis has been shown to provide natural frequency and mode shape estimates that are equivalent to those delivered through traditional modal analysis. However, the damping estimates from the technique are often inaccurate. This investigation focuses on the damping estimates delivered by traditional modal parameter estimation techniques when using output only data. Theoretical cases involving 5 degree-of-freedom and 15 degree-of-freedom systems are examined. Investigations into the effect of system damping and rank deficiency are also examined. 2010 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1291147391 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1291147391 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
