Design of Integrated Filter Module for Micro Aero-engine Vibration Signal

Abstract

Micro aero-engine is a branch of aero-engine that has a wide range of applications in various fields and is of high value. Micro aero-engine will produce vibration during operation, different vibration styles correspond to different operating conditions, and most faults are closely linked with mechanical movement or vibration. Through vibration detection can directly and real-time fault analysis. As the basic work of signal analysis, filtering is of great significance. By using LABVIEW2022 programming to develop filtering tools based on time-varying methods, continuous wavelet transform methods, and discrete wavelet transform methods, the comprehensive filtering of the signal is realized. Through the successful application of this technology, the conception is confirmed and the foun-dation is laid for the subsequent deep development. doi 10.54708/19926502_2024_28410652
