摘　　要：为快速、高效地排除复杂系统的振动故障,本文提出了振动故障模式的量化方法,可基于量化结果进行振动故障模式的重点验证。分析了振动故障树的技术特点,指出其不适用于复杂系统的振动故障分析;从故障模式的发生概率、故障模式的可验证性等维度对振动故障模式进行量化;结合某航空发动机核心机的振动故障,给出了振动故障模式量化方法的具体应用。实践证明振动故障模式的量化方法是可行、有效的,且具有较高的工程应用价值。To support the rapid and high-efficient elimination of the vibration fault of complex systems,this paper presents a quanti-tative method of vibration failure mode,which can realize the key verification of the vibration failure mode based on quantifiable value.The technical characteristics of the vibration fault tree analysis is discussed,which points out that fault tree analysis is not suitable for the vibration fault of complex systems.The quantification method of vibration failure mode is proposed,and dimen-sions of fault mode,like the probability of failure mode and the verifiability,are used to quantify.The vibration fault of the core ma-chine of an aviation engine is introduced,and the specific application of the method of vibration failure mode is given.It proves that the quantization method of vibration fault mode has the availability,high efficiency,and the important value of the engineering ap-plication.
