This paper aims at describing the architectural model of an adaptive force-feedback for a By Wire steering wheel system. This solution uses a steering wheel to replicate the reactive torque law which allows the driver to complete a precise driving scenario or a task with the higher performances. Then, the steering wheel adapts the reactive torque to the driving scenario. Since the design of thi...

Modern concepts of electrified drive trains for off-road vehicles allow for some new possibilities for control strategies. When considering traction efficiency, the most controllable factor is wheel-slippage. Many existing slip control systems use a certain threshold value of slip as reference, for example for farm tractors, electrohydraulic hitch control system (EHC) controls the implement, wh...

the ability to perform rolling contact fatigue (rcf) experiments in wheel–rail material is provided by a new small–scale test rig, manifesting the actual dynamic behaviour of the railway system. in this paper, a multi-body dynamics (mbd) model is proposed, simulating the vibration behaviour of the prescribed rig. the new testing facility is modelled using a three-dimensional model of the vehicl...

This paper presents a detection system for wheel billet end face angular deviation based on laser ranging method. Using three parallel lasers Irradiate the checking surface at the same time, the distance between the wheel billet end face and the laser sensors can be obtained, then the angle between the checking face and the reference plane is calculated by using the geometric theory and the sta...

we find an explicit expression of the tutte polynomial of an $n$-fan. we also find a formula of the tutte polynomial of an $n$-wheel in terms of the tutte polynomial of $n$-fans. finally, we give an alternative expression of the tutte polynomial of an $n$-wheel and then prove the explicit formula for the tutte polynomial of an $n$-wheel.

This paper presents a wheel–terrain interaction model, which enables efficient modeling of wheeled locomotion in soft soil and numerical simulations of off-road mobile robots. This modular model is derived based on wheel kinematics and terramechanics and the main focus is on describing the stress distributions along the wheel–terrain interface and the reaction forces exerted on the wheel by the...

This paper presents a new developed automated system used for flaw detection and classification on railway wheels. The described system uses the principle of non-destructive method based magnetic particle inspection. Our proposed and finally constructed automated system is used in industrial applications where non-destructive testing of railway wheels is desired. As a part of testing line, it i...

The endocannabinoid system serves many physiological roles, including in the regulation of energy balance, food reward, and voluntary locomotion. Signaling at the cannabinoid type 1 receptor has been specifically implicated in motivation for rodent voluntary exercise on wheels. We studied four replicate lines of high runner (HR) mice that have been selectively bred for 81 generations based on a...
