Basic Characteristics of Plastic Gears Lubricated with Water

JSME international journal. Ser. C, Dynamics, control, robotics, design and manufacturing, 1991
Recently, plastic gears have become to be used also in water, but according to the kinds of plastics, there are some which show a great deal of wear when they are used in water. However, it is considered also that in water or in the place where moisture exists, water performs lubricating action, and wear decreases as compared with the case without ...

Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

Advanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...
