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

Modified geometry of spur gear drives for compensation of shaft deflections [PDF]

, 2015
One of the main problems when standard spur gears are in mesh is the appearance of edge contact on the gear tooth surfaces caused by misalignments. Those misalignments are caused partially by deflections of gear supporting shafts.

A comprehensive review of haptic feedback in minimally invasive robotic liver surgery: Advancements and challenges

The International Journal of Medical Robotics and Computer Assisted Surgery, Volume 20, Issue 1, February 2024.
Abstract Background Liver medical procedures are considered one of the most challenging because of the liver's complex geometry, heterogeneity, mechanical properties, and movement due to respiration. Haptic features integrated into needle insertion systems and other medical devices could support physicians but are uncommon. Additional training time and
