| Abstract: | The squeeze-film dampers on model rotors and a real jet are studied experimentally and theoretically. It shows that it is possible to minimize the unbalance forces transmitted to the surrounding structure and the disc amplitude and to bring great potential of damper attenuation capability into full play if only the parameters of an uncentralized squeeze-film damper are chosen carefully. Generally speaking, the optimum damper design will achieve a reduction invibraton of 60% or more.A design method of uncentralized squeeze-film dampers is also recommended, which gives the bearing parameter B = 0.1 to 0.2 and the gravity parameter W = 0.05 to 0.1. The theoretical results and the experimental data have been found in good agreement. |
