Experimental and numerical investigations on vibration responses of shaft disc system

Abstract

Vibration in a mechanical system is not desirable and the interest newlinelies in reducing it by dissipation of vibration energy or damping newlineCharacterization of damping forces in a vibrating structure has long been an newlineactive area of research in structural dynamics Finite element method FEM newlinehas been widely used to investigate and analyze the vibration problems by the newlineresearchers for the past five decades This dissertation reports the studies on newlinenatural frequency and damping factor responses of shaft disc system with newlinedifferent constrained layer damping CLD The attention is focused on newlineexperimental and numerical investigation for vibrational characteristics of a newlinemild steel and composite sandwich shaft disc system with various newlinecombinations The CLD approach to minimize the vibration of a structure was newlinean interesting area of research in recent past years newline newline
