摘　　要：转子叶盘结构在高速和超高速的运行状况下,可能因为失稳而剧烈振动,进而引发严重的安全事故。增大叶盘结构阻尼是减轻其振动的有效方法之一。国内外学者针对叶盘结构,开展了大量的研究,为了充分了解叶盘结构减振方法的研究进展,推动相关问题的深入研究,提出了将叶盘结构减振分为干摩擦、内摩擦和其他能量转换方式。对叶盘结构减振方法的相关研究进展进行了总结,并展望了叶盘结构减振的未来研究方向。Rotor blisk structures may vibrate violently due to instability under high-speed and ultra-high speed operation conditions,which may lead to serious safety accidents Increasing the blisk structure damping is one of the effective methods for attenuating its vibration Scholars at home and abroad have conducted extensive research on blisk structures In order to fully understand the research progress of vibration attenuation methods for blisk structures and promote in-depth research on related issues,it is proposed to divide the vibration attenuation of blisk structures into three types,i e,dry friction,internal friction,and other energy conversion The research progress of vibration attenuation methods for blisk structures is summarized,and the future research directions of vibration attenuation for blisk structures are discussed.
