影响箔片结构阻尼的因素及箔片径向轴承结构形式的进展

Effects on the Damping of Foil Journal Bearings and the Development of the Foil Structure

稳定性是影响箔片轴承应用的一个关键问题,它与轴承弹性支承结构的阻尼特性密不可分。影响箔片阻尼的因素很多,内部因素如材料本身结构和性能,外部因素有温度、承载力和滑流等。本文介绍了箔片支承结构形式的进展,分析了影响箔片结构阻尼的几个外部因素,并结合实践提出改善箔片支承结构阻尼的几个途径。

Stability is one of the most important aspects to gas bearings＇ application. There are many factors affecting foil damping, such as the internal factors of the structure and performance of material, and external factors of temperature, load capacity and slip flow etc. The development of foil gas bearing was introduced, several external effects on the damping of foil bearings were analyzed, and several methods were brought forward to improve foil damping of elastic structure. Several external effects on the damping of foil bearings were analyzed, and several methods were brought forward to improve foil damping of support structure.
