摘要: 针对某型发动机振动问题,从振动特征上入手,存在两种振动特征:慢车上推高状态过程的过渡态振动偏大和慢车上推到高状态稳定后的振动偏大。分析了外场振动形式,结合当前发动机使用情况和相关类型整机振动特点,对发动机振动特征进行总结分析。统计了发动机在整个翻修期内历次过渡态和稳态振动最大值,以及典型发动机振动时间分布规律。最后,结合上述分析与统计结果,给出了某型发动机振动监控方案。所得振动标准为类似发动机的振动研究与故障排除起到应用参考作用。
Abstract: In this paper, aiming at the vibration problem of a certain type of engine, two kinds of vibration characteristics were obtained from the vibration in the process of pushing up on the idle and the larger vibration in the steady state on the idle. The vibration form of outfield was analyzed, ac-cording to the current engine usage and the vibration characteristics of the whole engine. The maximum values of transient and steady-state vibration and the vibration time distribution of typical engines during the refurbishment period were calculated. Finally, combined with the above analysis and summary, the vibration monitor scheme of a certain type of engine was given. The vibration standards obtained plays an application reference role in the research and trouble shooting of similar engine vibration.
