燃气轮机叶片轮盘振动特性分析

An Analysis of the Vibration Characteristics of a Gas Turbine Bladed Disc

对燃气轮机关键部件———叶片轮盘的振动特性和叶片轮盘振动的国内外研究状况作一简要综述 ,涉及单只叶片振动、轮盘振动、叶片 -轮盘耦合振动、带突肩和带冠叶片振动 ,以及共振和颤振等方面 ,同时给出了叶片和叶盘耦合系统振动特性计算分析的实例。

A brief survey is given of the current status concerning the research at home an d abroad of the vibration characteristics of a bladed disc, the key component of a gas turbine. The vibration characteristics studied in this paper pertain to t he following elements and components, a single blade, a turbine disc, a blade d i sc coupled system and shrouded blades. Also studied are the resonance and flutte r occurring in the above cited elements. In the meantime, a specific example fo r the calculation and analysis of the relevant vibration characteristics has been presented of the blade and blade disc coupled system.
