Abstract

ADJUSTMENT OF THE TRANSMISSIBILITY OF A SINGLE-DEGREE OF FREEDOM VIBRATING SYSTEM, PART I: UNIT TRANSMISSIBILITY

Prof. Galal Ali Hassaan*

ABSTRACT

The purpose of this paper is to present an efficient simple technique for the adjustment of the transmissibility of a single degree of freedom system through the optimal selection of one parameter which is the damping ratio of the vibrating system. As an application a case of constant unit transmissibility is considered with proper dynamics of the vibration amplitude ratio. Different objective function relationships are presented and the best one is assigned leading to exactly the desired unit force transmissibility and a frequency spectrum of the system vibration amplitude ratio having a settling frequency ratio as low as 0.038.
