Topic: Vibration Mitigation in Turbomachinery：The Non-linear Damper-Blade Matching May Boil Down to the Essentials

Speaker: Prof. Muzio M. Gola

Time: Tuesday, November 23, 2021, 19:00 - 21:00

Abstract:

In this presentation, Prof. Gola will give a general presentation of AERMEC research capabilities in dry-friction damping and underplatform dampers, and introduce PCR which greatly reduces the complexity of damper/blade matching. The presentation will introduce the main AERMEC test rigs, the numerical results against experimental results, the damper pre-optimization maps and a contact represented method. The presentation will introduce principle and realistic coupled optimization of PCR.
