2. Dissemination of analysis techniques

The main concepts of vibratory analysis have been around for generations. However, the mastery of vibratory aspects has only developed thanks to the concomitant dissemination of :

• finite element analysis software that is inexpensive and no longer requires special expertise to use;

• dynamic signal analyzers using Fast Fourier Transform (FFT – Fast Fourier Transform), which are also increasingly economical and easy to use.

The advent of a similar technological revolution in the field of sensors, thanks to thin-film silicon technologies, is helping to accelerate the spread of this trend.

The stakes are high, since this mastery of vibration and acoustics is the key to :

• lighter structures and machines,...
