由上海交大振动、冲击、噪声研究所和民航103厂合作完成的“АИ—24发动机振动故障研究”课题,获得了1987年中国民用航空局科技进步一等奖。该项成果是将振动信号的数字谱分析、时序建模与谱估计和试验模态分析等先进技术应用到航空发动机的故障诊断上,解决了民航系统多年存在的АИ—24发动机振动超差,频繁返厂维修的老大难问题,将振动故 The “АИ-24 Engine Vibration Failure Research” project jointly completed by Shanghai Jiao Tong University Institute of Vibration, Shock, Noise and Civil Aviation 103 won the first prize of science and technology progress of Civil Aviation Administration of China in 1987. This achievement applies the advanced technology of digital spectrum analysis, timing modeling and spectrum estimation and experimental modal analysis of vibration signal to the fault diagnosis of aeroengine, and solves the over-tolerance of АИ-24 engine vibration existed in civil aviation system for many years, Frequently return to the factory maintenance problems, it will vibration
