New Design of Hy-Vo Chain Based on the Ultra-Small Rolling Radius

open access: yesMachines, 2022
To improve the system meshing performance and the chain stability, a totally new type Hy-Vo chain with an ultra-small rolling radius is proposed in this research. According to the rolling theory of the rocker pin, the design method and the meshing system

Design and Analysis of Internal–External Composite Meshing Hy-Vo Chain

open access: yesApplied Sciences, 2023
The internal–external composite meshing mechanism should be the best way to improve the transmission performance of a silent chain drive, but there is no internal–external composite meshing Hy-Vo chain under the classical design approach.

Performance of urban mesh networks [PDF]

open access: yesProceedings of the 8th ACM international symposium on Modeling, analysis and simulation of wireless and mobile systems, 2005
Currently, large-scale deployments of mesh networks are being planned for Philadelphia as well as other cities. The performance of such networks has never been examined through simulation or through any other means. In this paper we perform detailed simulations of mesh networks in several urban environments and evaluate the performance of these ...

Performance Evaluation of a Mesh-Topology LoRa Network

open access: yesSensors, 2023
Research into, and the usage of, Low-Power Wide-Area Networks (LPWANs) has increased significantly to support the ever-expanding requirements set by IoT applications. Specifically, the usage of Long-Range Wide-Area Networks (LoRaWANs) has increased, due to the LPWAN’s robust physical layer, Long-Range (LoRa), modulation scheme, which enables scalable ...

Metrics for Performance Quantification of Adaptive Mesh Refinement [PDF]

open access: yesJournal of Scientific Computing, 2021
AbstractNon-uniform, dynamically adaptive meshes are a useful tool for reducing computational complexities for geophysical simulations that exhibit strongly localised features such as is the case for tsunami, hurricane or typhoon prediction. Using the example of a shallow water solver, this study explores a set of metrics as a tool to distinguish the ...

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

Development of a multiblock procedure for automated generation of two-dimensional quadrilateral meshes of gear drives [PDF]

open access: yes, 2020
This article describes a new multiblock procedure for automated generation of two-dimensional quadrilateral meshes of gear drives. The typical steps of the multiblock schemes have been investigated in depth to obtain a fast and simple way to mesh ...

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.
