The Attenuation of Flexural Waves in Mass Loaded Beams.

Abstract

This thesis experimentally tests the effects of resiliently mounted, independent masses on the propagation of flexural waves in a rectangular beam. The flexural waves are attenuated over a wide frequency band, and the magnitude and band of the attenuation is determined by the attached mass per unit length and the spring constant and resistance per unit length of the mounting material. The experimental results are compared with analytical predictions for the flexural wave attenuation. The results confirm the analytical model used and that the attached mass system acts as a dynamic absorber. (Author).
