CS27: Test set-up contribution into a generator mounted Epicyclic gear mechanical running test performance

Abstract

This case study is describing the observations and the troubles shooting relative to a mechanical runningtest carried out on a generator mounted Epicyclic gearbox The specific gear architecture is requiring a fullintegration into the generator frame, thus the use of a pedestal dummy system to replicate the generatorrotor and casing during the gear validation testThe authors will provide a comprehensive overview of the test bench set-up, test scope/procedure,findings and relevant corrective actions, with a deep dive on the lessons learnt about the observed modalstructure interactionsFinal recommendations will follow about the best practices to prevent similar systems interactions issues
