Automatic Scallion Seedling Feeding Mechanism with an Asymmetrical High-order Transmission Gear Train

Chinese Journal of Mechanical Engineering, 2020
The current automatic scallion-transplanting machine is a complicated mechanism composed of two linkage mechanisms and two band carriers. It delivers seedlings inefficiently because of the movement limitations of the linkage mechanism.

An analysis of fishing gear competition. Catalan fisheries as case studies

Scientia Marina, 2013
An asymmetric index was developed to measure the competition relationships among fishing fleets (or gears or métiers) in a multispecies fishery. This index can be used to measure the degree of dominance of each fleet and its level of independence from ...

A shape-independent analytical method for gear mesh stiffness with asymmetric spalling defects

Scientific Reports
Spalling, a common failure mechanism of gear systems, greatly affects the dynamics of gears operation, which is reflected in the time-varying mesh stiffness (TVMS). Current TVMS models often overestimate the asymmetric spalling phenomenon and may lead to
