Vibration Control Using Additive Damping and FFT Analysis 790220

With digital Fast Fourier Transform (FFT) analysis, which enables rapid identification of resonant frequencies, mode shapes, and modal parameters, a designer can optimize viscoelastic damping material applications for real structures. This paper will discuss the use of FFT analysis in the design of damping applications for eliminating resonant high cycle fatigue in specific light weight structural components.
