DYNAMIC MODEL OF VIBRATION ISOLATOR UNDER STATIC LOAD

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 companion publication. Experimental data are presented for both unfilled and filled natural rubbers, which shows satisfactory agreement with the model. The agreement is improved by the inclusion of a correction factor.
