Research on Establishment of Simulation Test Stand for Aero-engine Vibration Monitoring System
As one of the important means of engine fault diagnosis,the aero-engine vibration monitoring system has great significance in the field of aeronautics.In order to better understand the vibration characteristics of aero-engine,an aero-engine vibration monitoring system simulation test platform is designed and constructed.Firstly,typical characteristics and monitoring principle of aero-engine vibration are studied,model simplification is carried out,and a simulation test platform of engine vibration monitoring system is established by 3D printing.Then,the functions of vibration signal acquisition,speed measurement and speed control are realized by using STM32 slug and multi-module design.Finally,the collected data is imported into MATLAB for analysis,the functions of time and frequency domain analysis are realized by using its powerful computing ability.Practice shows that the platform has good teaching significance.
