Meshing Stiffness Calculation of Spur Bevel Gears Considering the Tooth Pair Coupling
In order to solve the problem of calculation efficiency and accuracy of time-varying meshing stiffness of spur bevel gears, a slice calculation method of meshing stiffness of spur bevel gears considering the coupling effect of tooth pairs is proposed ...

Condition Monitoring of Helical Gears Using Acoustic Emission (AE) Technology [PDF]
Techniques such as vibration monitoring, thermal analysis and oil analysis are well established as means to have been used to improve reliability of gearboxes and extend time-to-failure.

Experimental investigation on crack propagation paths in spur gears [PDF]
Spur gears subjected to bending fatigue may nucleate cracks at the tooth root fillet. In thin rim gears these cracks may propagate in a safe way (through the tooth) or in catastrophic way (through the rim).

Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Intermittent gear rattle due to interactions between forcing and manufacturing errors
The interaction between eccentricity and an external forcing fluctuation in gear rattle response is investigated experimentally. The experimental rig consists of a 1:1 ratio steel spur gear pair, the input gear being controlled in displacement and the ...

The impact of trauma‐informed teacher education
Abstract In this study, two cohorts of university students in an employment‐based teacher education course undertook trauma‐informed education training embedded within their coursework to enhance their preparedness to work with diverse learners and their self‐efficacy for trauma‐informed teaching. With increased calls for teacher preparation programmes

Condition monitoring of gearboxes using acoustic emission [PDF]
Acoustic emission (AE) is one of many technologies for health monitoring and diagnosis of rotating machines such as gearboxes. Although significant research has been undertaken in understanding the potential of AE in monitoring gearboxes this has been ...

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife
ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over
