Evaluation of Cushion Dynamic Properties by Impedance Measurements

CODEN: JTEVAB

Abstract

A method is proposed for the evaluation of cushions in dynamic environments. With the mechanical impedance technique the cushion properties are determined in terms of equivalent distributions of stiffness, damping, and mass parameters. Test results on a specific material show that these parameters may be considered of constant magnitude within limited ranges of frequencies and input levels. The equivalent cushion parameters are presented in dimensionless form as functions of the geometry and the input levels. The results warrant future tests at broader ranges of input and geometrical variables for further development of the method.
