A Novel Approach To Modelling And Simulation Of The Dynamic Behaviour Of The Wheel-Rail Interface [PDF]

, 2011
This paper presents a novel approach to modelling and simulation of the dynamic behaviour of rail-wheel interface. The proposed dynamic wheel-rail contact model comprises wheel-rail geometry and efficient solutions for normal and tangential contact ...

The role of the scale and the frequency bandwidth of steering wheel vibration on road surface recognition [PDF]

, 2006
Automobile drivers are regularly exposed to vibrational stimuli in their vehicle. Of the automobile subsystems, the steering wheel is one of the most important due to its role in controlling the vehicle.

Wheels on Wheels on Wheels—Surprising Symmetry

Mathematics Magazine, 1996
I was thinking of the curve traced by a particle on a wheel mounted on a wheel mounted on a wheel, each turning at a different rate. The first term represents the largest wheel, of radius 1, turning counter-clockwise at one radian per second. The second term represents a smaller wheel centered at the edge of the first, turning 7 times as fast.

Geometry-Encoded Actuation as a Structural Interaction Layer in Origami Robots. [PDF]

Adv Sci (Weinh)
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 ...

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Theoretical researches of a car wheel with a traction compensator

Trudy Odesskogo Politehničeskogo Universiteta, 2021
The rolling process of the wheel drive is accompanied by the loading of the wheel drive by the force of gravity, which leads to compression and stretching of the tire during its deformation.
