Dynamic Analysis of Structures Using Constrained Layer Damping Technique

Abstract

This Paper deals with the dynamic analysis of the structures designed to support engines are subjected to vibration due to dynamic excitations. When the exciting force is oscillatory, the system is forced to vibrate at the excitation frequency. If the frequency of excitation coincides with one of the natural frequencies of the system, a condition of resonance is encountered. In this paper an attempt is made to identifying suitable damping treatment for a motor driven compressor foundation used in marine structures. It involves to finding the natural
frequencies of the structural foundation. An experimental investigation is carried out to find the natural frequencies of structural foundation using FFT analyzer. The results obtained are compared with the results obtained from ANSYS.
