Optically trapped and driven paddle-wheel [PDF]
We demonstrate the control and rotation of an optically trapped object, an optical paddle-wheel, with the rotation direction normal to the beam axis. This is in contrast to the usual situation where the rotation is about the beam axis.

Net traction of a driven wheel as affected by slippage, velocity and wheel load
The objective was to assess the effect of velocity at three levels (i.e. 0.8, 1 and 1.2 m/s), slippage at three levels (i.e. 10, 12 and 15%) and three levels of wheel load (i.e.

A Parameter-Driven Methodology of Wheel Flat Modeling for Wheel–Rail Impact Dynamics
A wheel flat is a typical wheel defect that significantly impacts the wheel–rail system, posing substantial challenges to vehicle operation safety. In the existing literature, the wheel flat plane model does not account for the contribution of the width ...

Intelligent mobility control of a hybrid electric off-road vehicle with individual wheel control [PDF]
This work focuses on the potential benefits that can be gained from the use of Individual Wheel Control on a large off-road vehicle. The vehicle concerned is a theoretical, six-wheel drive, off-road Hybrid-Electric Vehicle based on an existing ...

Geometry-Encoded Actuation as a Structural Interaction Layer in Origami Robots. [PDF]
We present geometry‐encoded actuation (GEA), a design framework that integrates multistable origami with liquid crystal elastomer actuators to encode environmental interactions into autonomous structural responses. GEA enables programmable shape transformation without continuous sensing or complex control, achieving robust adaptive manipulation and ...

Modelling the Dynamic Behaviour of the Wheel-Rail Interface by Using a Novel 3D Wheel-Rail Contact Model [PDF]
Methods for multibody modelling and simulation should accurately replicate the dynamic behaviour of rail-wheel interface including precise values for wheel-rail contact positions. This paper studies the development of a novel 3-D wheel-rail contact model

On the near wake of a Formula One front wheel [PDF]
Velocity measurements were made in the near wake of the front wheel of a Formula One car using a laser Doppler anemometer. Tests were carried out on a 50% scale in a closed-return three-quarter open-jet wind tunnel. Three configurations were investigated

The Effect of Profiles on Wheel and Rail Damage [PDF]
This paper outlines the historical development of the wheel and rail profiles currently used on railway vehicles. It also presents the key damage mechanisms involved in wheel-rail contact and summarises the methods that have recently been developed by ...
