✦ Synopsis

A two-mass method is proposed to determine the four-pole parameters of a uni-directional asymmetrical vibration isolator. It may be regarded as a universal testing procedure applicable to uni-directional or bi-directional, and asymmetrical or symmetrical vibration isolators under static load. Generally, vibration isolators incorporating some form of active control are examples of uni-directional asymmetrical vibration isolators. Experimental data are presented that validate the two-mass method.

This study investigates a dynamic model of a vibration isolator as a function of the compression ratio of its rubber element. The model is in terms of the four-pole parameters, and is based on a relationship between the phase velocity and compression ratio of the rubber element proposed in a compani
