摘要/Abstract

摘要： 对叶片涂敷NiCoCrAlY+YSZ硬涂层，研究具有硬涂层的大小叶盘的动力学模型和振动特性，主要研究硬涂层对大小叶盘的阻尼减振性能的影响.首先，利用复模量理论和Oberst梁理论，建立了涂层大小叶盘结构的解析模型;然后，基于Gram-Schmidt法和Rayleigh-Ritz法，求解涂层大小叶盘结构的模态特性和受迫响应.结果表明:硬涂层阻尼对大小叶盘固有频率的影响很小，但能使模态损耗因子提高4倍，说明硬涂层可以有效提高大小叶盘的阻尼性能;此外，涂敷硬涂层可以有效抑制其受迫响应.

关键词: 大小叶盘, 硬涂层阻尼, 被动减振, 解析建模, 受迫响应

Abstract: The blades were coated with NiCoCrAlY+YSZ， then the dynamic model and vibration characteristics of the hard-coated splitter blisk were investigated， as well as the effect of hard coating on damping vibration reduction of the splitter blisk. Firstly， analytical model of the hard-coated splitter blisk was obtained using the complex modulus and the Oberst beam theories. The mode characteristics and forced responses of the hard-coated splitter blisk were then solved using the Gram-Schmidt process and Rayleigh-Ritz method. The results reveal that hard coating has a weak effect on natural frequencies of splitter blisk but makes the modal loss factors increase about four times， which explains that hard coating can effectively improve the damping performance of the splitter blisk. Moreover， the forced response can be suppressed remarkably.

Key words: splitter blisk, hard coating, passive vibration reduction, analytical modeling, forced response
