- 01HBZEECNK6BJCQXY26WXMMS6T abstract "The study of dynamics of rotating machinery has risen to be of great importance in recent decades, with the industry vying for higher operating speeds, higher loads, and lower weight. This trend tends to place the system in the vicinity of its critical speeds, limiting its operational potential, and the traditional approach to reduce vibrations is to attach a tuned mass damper to the system. However, these are tuned based on 1:1 resonance of the system and fail to work effectively otherwise. Accordingly, recent developments have seen the use of the Nonlinear Energy Sink (NES) as their substitute, providing a more robust means of vibration mitigation, by being functional for a broad range of frequencies. In this paper, a passive vibration absorber with nonlinear stiffness is attached to a simple Jeffcott rotor. A speed-dependent force due to mass eccentricity is used here, as is common in rotordynamic systems. The conventional hardening (cubic) stiffness and a newly introduced softening stiffness are studied for their feasibility and compared against each other based on their behaviour and performance. The system’s frequency response is obtained using first-order harmonic balancing and the stability of the solution branches is studied using the multiple time-scales method. Furthermore, a parametric study of the response behaviour and NES performance for various stiffness characteristics is presented. With these methods, one can effectively prove the feasibility of using NESs for vibration mitigation in rotor systems.".
