摘要
Abstract
In order to reduce the vibration of a 600 MW turbine generator, the scaled model which has the same modals with the generator base, was established. Using this model, a comprehensive experimental study of the effect of the particle damper on the vibration of the 600 MW turbine generator was carried out. In addition, the performances of vibration reduction for the single-layer/double-layer structure and different types of particles were compared. It shown that the particle damper, which employs the collision, friction and momentum exchange as its damping mechanism, has good damping effect. The maximum amplitude reduction is more than 60 %. Under certain conditions, the damping effect of the double-layer particle damper is better than that of the single-layer particle damper. Different types of particle dampers have different damping effects. The particle damper has a broad application prospect on vibration reduction of turbine generators.关键词
