Transformation of auxiliary mass response in dual-stage suspension for reduced vibration

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

This work introduces a method of mechanically transforming the vibratory interaction between the auxiliary mass and the base of a dual-stage suspension to further reduce vibration under certain operating conditions. In the case of a vibratory force input to the primary mass, the transformation establishes a frequency where the force transmitted to the base will be zero (neglecting damping). Around this frequency of zero-force transmission there is a bandwidth of frequency where the transmitted force is lower than what it would be with a corresponding dual stage suspension. Further, properties can be chosen such that the transformation has a lower force transmission than the corresponding single degree-offreedom suspension for the whole range of frequencies in the isolation region. Similar behavior occurs in the case of a vibratory displacement input to the base.
