The vibration problem of discs and bladed discs is one of the most important problem in the field of aero turbomachinery engineering. Many investigations have been carried out to predict the vibration characteristics of discs and bladed discs. In the last decade, with the development of aero engine techniques and finite element methods, the vibration analysis techniques of discs and bladed discs have been developed rapidly. Various vibration analysis techniques of discs and bladed discs developed in foreign countries are summed up in this paper. Among them, the finite element method is considered to be the most efficient method. In recent years, some new type elements (such as annular elements, sector elements, etc) have been developed. A large number of computer storages and computing time can be saved, if the above elements are used to predict the vibration characteristics of discs and bladed discs. So these elements are vevy useful for the study of the vibration of bladed disc assemblies. In this paper more than 40 references are introduced and they are valuable for invest tigating the disc and bladed disc assembly vibration characteristics.

轮盘及带叶片轮盘的振动问题是航空涡轮机工程发展中最重要的问题之一。为了计算轮盘及带叶片轮盘的振动特性,人们已经进行了许多研究工作。近十年来,随着航空发动机技术以及有限元方法的发展,轮盘及带叶片轮盘的振动分析方法有了很大的发展。本文综述了国外有关轮盘及带叶片轮盘的各种振动分析方法。其中,有限元素法为最强有力的一种分析方法。近年来,在有限元素法中发展了一些新元素(如环形元素,扇形元素等)。若用这些元素来计算轮盘和带叶片轮盘的振动特性,可以大量节省计算机的存贮量和计算时间。因此它们对研究带叶片轮盘组合件的振动是十分有用的。本文介绍了40多篇文献。它们对研究轮盘及带叶片轮盘组合件的振动特性是很有价值的。
