Abstract
This paper presents an analysis of vibration-induced fatigue in a generalized, two degree-of-freedom vibration isolation system. The system consists of a source body and a receiving body, coupled through a passive isolator. The isolator consists of a spring, a damper, and an inerter. A broad frequency band excitation of the source body is assumed. Optimized system, in which the kinetic energy of the receiving body is minimized, is contrasted to two sub-optimal systems. This is done by comparing fatigue life of a helical spring in the system for four cases. The optimization is based on minimizing vibrations, but it also increases the number of cycles to failure of the considered spring. A significant portion of this improvement is due to the inclusion of an optimally tuned inerter in the isolator.
