Vibrational Analysis of the Flexing Head of the BQS-6 Transducer.
Abstract
The purpose of the work in this report was to develop a finite-element mathematical model for the equations of motion that are related to the BQS-6 transducer's flexing head. Results showed that holographic interferometry is an extremely sensitive and accurate experimental technique for measuring the small displacements of vibrating systems and that the finite-element method is an excellent tool for theoretically predicting this behavior. The finite-element ansatz predicted all measured resonant frequencies within 5 percent. Predicted mode shapes could not be distinguished from those measured by holographic interferometry. (Author)
