Abstract

This paper deals with Theoretical and Experimental methods for identification of coulomb ,Viscous and Particle damping parameters from the response of Single degree of freedom harmonically forced linear oscillator when system damped with more than one type of damping , which parameter is r esponsible for the control of resonant response of vibrating systems , in experimental method setup have been presented to investigate steady state response amplitude x i f or SDOF system for different values of amplitude Y i of the base excitation from this relationship of (X i , Y i ) the values of viscous damping coefficient „c? and coulomb friction force F 0 , also equivalent viscous damping ratios , have been calculated from frequency response analysis for the systems with viscous damping ,Viscous and Coulomb friction damping , coulomb friction damping and particle damping by using half power band - width method and in theoretical studies expression for steady state amplitude X 0 obtained is used to study the effect of frequency ratio and coulomb friction parameters on phase angle and amplitude ratio
