The application of vibration acceleration sensor in aero engine is mainly reflected in the real-time monitoring and analysis of engine vibration characteristics. During the operation of aero-engine, vibration will occur due to various factors, such as rotor unbalance, blade vibration and structural loosening. These vibrations may not only affect the performance and lifespan of the engine, but also pose a threat to the stability and safety of the whole machine
The vibration acceleration sensor can effectively capture and analyze various vibration information of the engine by measuring the vibration acceleration of the engine in real time. Specifically, these sensors can：
Monitoring vibration status: By measuring the vibration acceleration of the engine under different working conditions, it can be determined whether the engine is in normal working condition. When the engine experiences abnormal vibrations, sensors can quickly capture these changes，which provides an important basis for fault warning and diagnosis.
Analyze the cause of vibration：hrough the analysis of vibration acceleration data,the source and type of engine vibration can be identified,such as rotor imbalance, blade vibration, structural resonance, etc. This helps engineers to develop corresponding solutions to specific problems and improve the reliability and stability of the engine.
Evaluate the impact of vibration:Vibration acceleration data can also be used to assess the impact of vibration on engine performance and life.Through the analysis and processing of the data, the evaluation results of fatigue damage and wear degree of engine parts caused by vibration can be obtained, which provides scientific basis for engine maintenance and maintenance.
In addition, vibration acceleration sensors also have the characteristics of small size, light weight, and easy installation, which can be arranged in various positions of the engine to achieve comprehensive monitoring of engine vibration characteristics. At the same time, with the continuous development of sensor technology, its measurement accuracy and stability are also improving, which provides a strong guarantee for the safe operation of aircraft engines.
It should be noted that when using vibration acceleration sensors for aircraft engine vibration monitoring, other sensors and testing equipment such as temperature sensors, pressure sensors, displacement sensors, etc. need to be combined to obtain more comprehensive engine status information. At the same time, it is necessary to process and analyze sensor data reasonably to extract useful vibration feature information, providing strong support for engine fault diagnosis and performance optimization.
