Experimental Modal Analysis on Automotive Development
SAE Technical Paper Series, 2003<div class="htmlview paragraph">In the last years, vehicle vibroacoustics has expanded as a basic and applied research area. Structural dynamic methods and technologies have been used with great success by the automotive industry. Experimental modal analysis is the process of determining the modal parameters (modes, frequencies and damping ...

Signal processing for experimental modal analysis
Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2001Summary: This paper is an overview of signal processing for modal analysis. The approach taken is to summarize some of the types of data that arise in modal analysis, to classify signal processing problems, and to attempt to show the relevance of the latter to the former.

Modal Truncation in Experimental Modal Analysis
2018Some methods in experimental modal analysis rely on a finite set of modes and they neglect the higher modes. However, this approach causes a truncation of the modal decomposition and the modal truncation introduces errors of unknown magnitude. In this paper the effect of modal truncation is investigated on a test specimen in the laboratory. It is found
