Research on Gear Box Fault Diagnosis Technology Based on PCA‐EDPSO‐BP Neural Network
IET Collaborative Intelligent Manufacturing, Volume 7, Issue 1, January/December 2025.This paper takes the gear of the gearbox as the research object, and uses the deep learning model to analyse the gear operation data to realise the intelligent diagnosis and prediction of gear faults. ABSTRACT As a key transmission component, the gear failure (such as broken teeth, wear, pitting, etc.) of the gearbox can easily lead to equipment ...

International Journal of Aerospace Engineering, Volume 2025, Issue 1, 2025.This study explores the impact of flap gaps on aircraft cabin vibrations, focusing on the dynamic responses of flap structures under aerodynamic excitations. Flaps are crucial for aircraft control, especially during takeoff and landing. Common issues in flap systems, such as wear on slide tracks, bearing clearances, and bushing slippage, introduce gaps
