2015 年 河 北 科 技 大 学 学 报 第36 卷 文章编号:1008-1542(2015)00-0001-00 doi:10.7535/hbkd.2015yx 失谐叶盘结构减振问题研究综述 张 亮,刘铁箭,李 欣,霍绪尧 （辽宁工业大学机械工程及自动化学院，辽宁锦州 121001） 摘 要：叶盘结构是航空发动机、燃气轮机的重要零部件，在工程实际中应用广泛。由于失谐普遍存在于叶 盘结构中，并且会破坏叶盘系统原有振动特性，是导致叶盘高周疲劳失效的原因之一，因此研究如何降低叶 盘结构振动是非常有必要的。目前国内外有很多学者对此作了一系列研究，从不同方面探究叶盘系统的减振 措施。在本文中说明了叶盘结构失谐振动的机理，并结合现阶段的研究成果，介绍了失谐叶盘系统减振的研 究现状，如人为主动失谐、碰撞阻尼、摩擦阻尼、优化叶片安装排序减振等，并提出了一些今后的研究方向。 关键词：失谐叶盘结构；碰撞阻尼；摩擦阻尼；优化算法 中图分类号：V232.3 文献标志码：A A Review of Research on Vibration Damping of Mistuned Bladed Disk Assemblies ZHANG Liang, LIU Tiejian, LI Xin, HUO Xuyao (Faculty of Mechanical Engineering and Automation, Liaoning University of Technology, Jinzhou, Liaoning 121001 China) Abstract ：Bladed disk assemblies are very important parts in auto engine and gas turbine, which has very important applications in practical engineering. As the mistuning is common in the bladed disk assemblies, the vibration characteristics of the bladed disk assemblies are destroyed. It is one of the reasons for the high cycle fatigue failure of bladed disk assemblies, so it is necessary to research how to reduce the vibration of the bladed disk assemblies. Currently there are many domestic and foreign scholars have made a series of studies. Studied from different aspects in different ways have reached the damping effect of bladed disk assemblies. In this paper, the mistuning vibration mechanism of the bladed disk assemblies is explained, and combining the current research results, the research status of the vibration damping of bladed disk assemblies are introduced, such as artificially active mistuning,
