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 ...

Computation of Vibration Response of Aircraft Due to the Gap Between the Track and Roller in the Flap Subjected to Unsteady Flow

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

Theoretical and experimental working life comparison for a helical gear under linear pitting failure [PDF]

, 2007
For machine components like gears and bearings, working life calculation is one of the complex issues to deal with. This is because the mechanics of their operation is dependent on many parameters, like loading, friction and lubrication etc.
