Experimental Modal Analysis - Sound and …
1 Sound AND VIBRATION/JANUARY 2001 Often times, people ask some simple questions regardingmodal Analysis and how structures vibrate. Most times, it isimpossible to describe this simply and some of the basic un-derlying theory needs to be addressed in order to fully explainsome of these concepts. However, many times the theory is justa little too much to handle and some of the concepts can bedescribed without a rigorous mathematical treatment. Thisarticle will attempt to explain some concepts about how struc-tures vibrate and the use of some of the tools to solve struc-tural dynamic problems. The intent of this article is to sim-ply identify how structures vibrate from a nonmathematicalperspective. With this being said, let s start with the first ques-tion that is usually asked:In a nutshell, we could say that Modal Analysis is a processwhereby we describe a structure in terms of its natural char-acteristics which are the frequency, damping and mode shapes its dynamic properties.
2 SOUND AND VIBRATION/JANUARY 2001 the measured time data is transformed from the time domain to the frequency domain using a Fast Fourier Transform algo-
