Abstract
This paper presents a theoretical and experimental study of the transmission of vibration through a two element structure which consists of a cylindrical shell couple to an end plate. The first part of this paper deals with the derivation of coupling loss factor (CLF) for the study of vibration transmission using Statistical Energy Analysis (SEA). The derivation is based on travelling wave analysis and the assumption of equipartition of energy amongst resonant modes. Numerical results for three examples of cylinder/plate structures are presented and compared with those of their equivalent plate/plate structures. The results show that the CLF values of the cylinder/plate structures asymptote to their equivalent plate/plate structures above the ring frequency of the cylinder. In the second part of this paper, an experimental program for measuring the CLF of an example cylinder/plate structure is described. Experimental results of the cylinder/plate structure show good agreement with theoretical predictions and confirm the validity of the present formulation of CLF.
