Chaotic dynamics of spiral bevel gears

International Journal of Non-Linear Mechanics
This study investigated the nonlinear dynamics of a Spiral Bevel Gear (SBG) system used in helicopter transmissions. Two approaches were employed to determine the Mesh Stiffness (MS): the average slope method (average-MS) and a hybrid analytical-computational method (adaptive-MS), which accounts for Hertzian contact nonlinearity. The dynamic mesh force

A 3D Printing Strategy for Hard Curved Surfaced Circuits: From Materials to Applications

Advanced Science, Volume 12, Issue 36, September 25, 2025.
Conventional PCB etching (multi‐step) and indirect transfer techniques fail to meet structural electronics’ demands for lightweight, miniaturized, and customized manufacturing. 3D‐printed conformal circuits enable direct integration of conductive traces into substrates or onto surfaces, achieving integrated structural‐functional fabrication.

Pitting failure of truck spiral bevel gear

Engineering Failure Analysis, 2007
Abstract Spiral bevel gears are some of the most important elements used in truck differential. In this study, the fracture of spiral bevel gear for truck differential produced from case hardening steel is investigated. In order to study the causes of the failure, specimens prepared from the damaged spiral bevel gears were subjected to experiments ...

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
