Discrete Singular Convolution for Free Vibration Analysis Annular Membranes [PDF]

open access: yesMathematical and Computational Applications, 2009
In this paper, we investigate the effects of some geometric parameters and density variation on frequency characteristics of the annular membranes with varying density. The discrete singular convolution method based on regularized Shannon’s delta kernel is applied to obtain the frequency parameter.

Discrete Singular Convolution Method for Acoustic Transmission Lines

open access: yesAcoustics Australia, 2020
Discrete singular convolution (DSC) algorithm is an accurate dynamic analysis method for single structures. However, vibration analysis of connected structures via the DSC method is limited to step beams and plates. This paper extends the applicability of the DSC method in handling acoustic transmission lines composed of several duct elements with ...
