摘要
介绍了某型涡轮轴发动机的振动特点，针对其空中、地面的振动频谱分布情况，提出了实施振动监测的方法。结合部队外场的实际情况，利用单片微机研制出适合外场地面、空中使用的振动监测仪，收到了较好的效果。
The Vibration characteristics of the turboshaft engine on ground and in flight are considered.According to the distribution of the vibration frequency spectrum,a method is presented to display and record vibration velocity value of the turboshaft engine on ground or in flight.A vibration monitor made of INTEL 51 series 8031 single chip microcomputer has eight channels.Six channels are employed to record vibration signals and the other two channels to measure engine rotating speeds.The system operation performance has been proved by a large amount of measurements on fields and airbrone measrements.
