Study on the Influence of Gear Spoke Hole Numbers on Meshing Noise

open access: yesApplied Sciences, 2022
Gear meshing stiffness is one of the important causes of noise, and the structure optimization of gears, such as spoke hole structures, has been proven to be an effective method to reduce gear meshing noise.

MESHING PERFORMANCE ANALYSIS OF TAPERED ROLLER ENVELOPING END FACE MESHING WORM DRIVE (MT)

open access: yesJixie qiangdu, 2023
The end face meshing worm drive with tapered roller envelope has many simultaneous meshing tooth pairs and can eliminate clearance. According to the gear meshing principle and differential geometry principle, the meshing mathematical model of the ...

High-resolution 3D weld toe stress analysis and ACPD method for weld toe fatigue crack initiation [PDF]

open access: yes, 2019
Weld toe fatigue crack initiation is highly dependent on the local weld toe stress-concentrating geometry including any inherent flaws. These flaws are responsible for premature fatigue crack initiation (FCI) and must be minimised to maximise the fatigue

JIGSAW-GEO (1.0): locally orthogonal staggered unstructured grid generation for general circulation modelling on the sphere [PDF]

open access: yes, 2017
An algorithm for the generation of non-uniform, locally-orthogonal staggered unstructured spheroidal grids is described. This technique is designed to generate very high-quality staggered Voronoi/Delaunay meshes appropriate for general circulation ...

Meso-scale modelling of 3D woven composite T-joints with weave variations [PDF]

open access: yes, 2019
A meso-scale modelling framework is proposed to simulate the 3D woven fibre architectures and the mechanical performance of the composite T-joints, subjected to quasi-static tensile pull-off loading. The proposed method starts with building the realistic

Numerical simulation of three-phase flow in an external gear pump using immersed boundary approach [PDF]

open access: yes, 2019
This paper presents a three-phase fully compressible model applied along with an immersed boundary model for predicting cavitation occurring in a two dimensional gear pump in the presence of non-condensable gas (NCG).

Sludge thickening performance of mesh filtration process

open access: yesWater Science and Technology, 2004
Small-scale wastewater treatment facilities play an important role in improving the aquatic environment in many countries. Although sludge treatment is essential for overall wastewater treatment, it is difficult for small-scale facilities to use mechanical equipment or other facilities.
