Design, analysis, and experimental validation of a novel seamless automatic transmission for electric vehicle

open access: yesAdvances in Mechanical Engineering, 2018
The transmission system has an important influence on the dynamic performance, endurance mileage, and energy saving in an all-electric vehicle. This article proposes an innovative two-speed seamless dry-friction automatic transmission system to improve ...

Friction-Active Surfaces Based on Free-Standing Anchored Cellulose Nanofibrils

open access: yes, 2018
A specific feature of fibrous surfaces is the dependence of their mechanical properties on the alignment of the fibers. Vertically aligned fibers enhance friction and adhesion, whereas horizontal fibers are known to act as a lubricant reducing the ...

Skin‐Like Tri‐Modal Sensors Based on Soft Piezoelectric and Ionic Composites

open access: yesAdvanced Materials Technologies, EarlyView.
Inspired by the multimodal perception of human skin, a soft, skin‐like tri‐modal sensor is presented. The device incorporates an ionically conductive, piezoelectric, elastic composite as its active layer, enabling independent detection of temperature, static strain, and dynamic strain within a single two‐terminal architecture.

A study of dry frictional contacts

open access: yes, 1994
This study addresses a range of phenomena associated with dry frictional contacts. Particular emphasis is devoted to elastic dissimilarity. Problems are formulated such that coupling between normal and tangential tractions is permitted and the results, which must often be found by numerical means, are compared with classical solutions. The manipulation

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

open access: yesAdvanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

On the multi-scale nature of ski-snow friction in cold conditions [Elektronisk resurs]

open access: yes
In the Olympic winter sports cross-country skiing and the biathlon, athletes aim to minimise resistive forces such as aerodynamic drag, gravity, and ski–snow friction to enhance performance.
