Dynamics analysis of hyperboloidal-type normal circular-arc gears

open access: yesNantong Daxue xuebao. Ziran kexue ban
To investigate the effects of meshing stiffness, transmission error, and backlash on the dynamic response of hyperboloidal-type normal circular-arc gears(HNCGs), a dynamical equation of the gear pair is established, and simulation analysis is conducted ...

Calculation Model of Time-varying Meshing Stiffness of Planet Gear Pitting Fault based on Full Tooth Profile

open access: yesJixie chuandong, 2021
When a gear has a pitting fault,the vibration response characteristics caused by its time-varying meshing stiffness change is an important basis for the diagnosis of pitting faults,and an accurate gear geometry model is of great significance for the ...

A computer solution for the dynamic load, lubricant film thickness and surface temperatures in spiral bevel gears [PDF]

open access: yes
A complete analysis of spiral bevel gear sets is presented. The gear profile is described by the movements of the cutting tools. The contact patterns of the rigid body gears are investigated. The tooth dynamic force is studied by combining the effects of

Finite Element Modeling of the Transition Zone between Aggregat and Mortar in Concrete [PDF]

open access: yes, 2012
Visual observations to the Interfacial Transition Zone (ITZ) between aggregate and mortar in concrete showed that this area differs significantly to the bulk mortar, further away from the ITZ.

Modelling of Elastic Gearboxes Using a Generalized Gear Contact Model [PDF]

open access: yes, 2012
The object of this paper is to present an universal model that describes the gear contact between two gears in a planar environment. The model includes elastic effects between the gear wheels.

Endothelial Cells Angiogenesis in Sulfated Glycosaminoglycan (GAG) Hydrogels Enhanced by Bioactive Glass‐Released Ions

open access: yesAdvanced Functional Materials, EarlyView.
A mechanically tunable hydrogel composed of gelatin, chondroitin sulfate and laminin promotes angiogenesis in vitro without the supplement of growth factors. Endothelial cells morphogenesis was further enhanced by medium conditioned with bioactive glass 58S‐released ions (Ca and Si), thus offering a promising strategy to vascularize 3D tissue ...

Effect of extended tooth contact on the modeling of spur gear transmissions [PDF]

open access: yes
In some gear dynamic models, the effect of tooth flexibility is ignored when the model determines which pairs of teeth are in contact. Deflection of loaded teeth is not introduced until the equations of motion are solved.

Wrinkling in engineering fabrics: a comparison between two different comprehensive modelling approaches [PDF]

open access: yes, 2018
We consider two ‘comprehensive’ modelling approaches for engineering fabrics. We distinguish the two approaches using the terms ‘semi-discrete’ and ‘continuum’, reflecting their natures.
