  1. Novel Topologies for Active Vibration Management in Flexible Rotors Supervisors Patrick KEOGH Necip SAHINKAYA Researcher Chris LUSTY University of Bath UKACC PhD Presentation Showcase

  2. Introduction • Vibration is a major consideration in the design of rotating machinery • This is especially the case where high speed rotation is involved • Improving the ability to handle vibrations opens up new possibilities in machine design UKACC PhD Presentation Showcase

  3. The Problem • Excessive vibration at certain “critical speeds” can lead to machine damage / failure • Critical speeds are a function of rotor properties • Look to alter rotor properties in such a way as to shift critical speeds UKACC PhD Presentation Showcase

  4. The Problem • A preferable vibration response is shown here: UKACC PhD Presentation Showcase

  5. The Proposed Solution • The solution is conceptually inspired by tuned mass damping UKACC PhD Presentation Showcase

  6. The Proposed Solution • A practical rig has been designed to test the merit of the idea UKACC PhD Presentation Showcase

  7. The Proposed Solution • A practical rig has been designed to test the merit of the idea UKACC PhD Presentation Showcase

  8. Conclusion or summary or future work • A novel topology has been proposed to reduced vibration amplitudes in flexible rotors • It has been shown to be promising by FE analysis • A rig has been designed to practically test the idea • The rig is designed to be progressive, enabling increasingly complex testing to explore the scope of the idea UKACC PhD Presentation Showcase
