The invention relates to the technical field of aero-engines, and discloses an aero-engine vibration steady-state working condition identification method, which is used for judging whether the state of an engine is a steady state or not based on the change rule of the rotating speed, and dividing the working conditions according to the average rotating speed of the steady state and the rotating speed change rule between the working conditions. According to the method, the problems of misjudgment, repeated transverse jumping of the state and the like in the prior art are solved.
本发明涉及航空发动机技术领域,公开了一种航空发动机振动稳态工况的识别方法,基于转速的变化规律判定发动机状态是否为稳态,并根据稳态的平均转速、工况间的转速变化规律进行工况的划分。本发明解决了现有技术存在的出现误判、状态的反复横跳等问题。
