Abstract This study investigates the influence of local hybridization Thin and Thick-Ply CFRP laminates on open-hole bearing properties. The area weight unidirectional prepregs used is 40 gsm in case Thin-Ply layers 160 gsm layers. steel a 1.4310 stainless-steel foil with same layer thickness as prepregs. In hybrid area, 90 ∘ were locally replaced by stainless patches. metal content varies from...

This article presents an experimental study carried out on a rotor operating two foil bearings. One of the bearings was built in way to measure temperature and deformation top bearing. The dynamic performance bearing journals is presented herein using vibration trajectories journal positions sleeve. Based these results, method for predicting distribution developed. Then, correlations between pa...

Gas foil bearing rotor (GFBR) systems have received significant interest in the field of rotordynamics and vibration analysis. GFBR a wide range high-speed turbomachinery applications. Due to high speed, these machines are susceptible rigorous instability. bearings instigate large amplitude vibrations at startup shut down severe subsynchronous motions during operations. Over years, numerous wor...
