摘要
转静子碰摩问题是发动机在过渡态时发生振动超标故障的主要原因之一,为了对其进行更为有效地考核验证与分析,从碰摩实验装置、测试技术及涂层可磨耗试验验证方面阐述了国内外目前的研究现状,并分析了主要差距。结合发动机真实工况,提出了碰摩试验的发展需求。本文研究对于发展我国军/民用航空发动机封严涂层适航审定技术具有重要的工程指导意义。
The static rotor rub-impact problem is one of the main reasons of vibration over-standard failure during transition mode of engine.In order to carry out more effective assessment verification and analysis,the current domestic and abroad research status in the aspects of friction test device,test technology and coating wear test verification is described,and the main difference is analyzed.In combination with the real operating conditions of the engine,the development needs of friction test are put forward.This study is of important engineering guidance for development of military/civil aviation engine sealing coating airworthiness validation technology.
