Control Strategy of the Brake Dynamics for Railway Vehicles Equipped with Anti-Slip-Device [PDF]

open access: yes, 2006
From the point of view of railway vehicle braking processes it is an important requirement to maintain the roll-ing-motion-state of the wheels, i.e. the macro-sliding-free rolling contact between the vehicle wheels and the rail-head, since in the course ...

REGRESSIVE ANALYSIS OF BRAKING EFFICIENCY OF M1 CATEGORY VEHICLES WITH ANTI-BLOCKING BRAKE SYSTEM [PDF]

open access: yesAvtomobilʹnyj Transport (Harʹkov), 2015
The problematics of assessing the effectiveness of vehicle braking after road accidentoccurrence is considered. For the first time in relation to the modern models of vehicles equipped with anti-lock brakes there were obtained regression models ...

Wind braking of magnetars: to understand magnetar's multiwave radiation properties

open access: yes, 2014
Magnetars are proposed to be peculiar neutron stars powered by their super strong magnetic field. Observationally, anomalous X-ray pulsars and soft gamma-ray repeaters are believed to be magnetar candidates.

Synergetic theory for jamming transition in traffic flow

open access: yes, 2000
The theory of a jamming transition is proposed for the homogeneous car-following model within the framework of Lorenz scheme. We represent a jamming transition as a result of the spontaneous deviations of headway and velocity that is caused by the ...

Effect of Gap Clearances in Automatic Coupling Devices on Longitudinal Forces in Intercar Connections of Homogeneous Train

open access: yesМеханика машин, механизмов и материалов, 2019
A computer simulation of transient processes is performed that occur in the train intercar connections at starting from standstill, transition to idling and electrodynamic braking by the locomotive on a straight horizontal section of the railway track ...

Pin-on-Disc Experimental Study of Thermomechanical Processes Related to Squeal Occurrence

open access: yesLubricants
Squeal refers to a sustained high-intensity noise resulting from friction-induced vibrations. Although it is known that it originates from mode coupling, the conditions under which it occurs are still unclear, especially regarding the contact conditions.

Magnetic Braking and Viscous Damping of Differential Rotation in Cylindrical Stars

open access: yes, 2003
Differential rotation in stars generates toroidal magnetic fields whenever an initial seed poloidal field is present. The resulting magnetic stresses, along with viscosity, drive the star toward uniform rotation.

Experimental Evaluation of Effect of Leaves on Railroad Tracks in Loss of Braking

open access: yesMachines
This study aims to comprehensively assess the lubrication effect of leaves on wheel–rail contact dynamics using the Virginia Tech-Federal Railroad Administration (VT-FRA) Roller Rig, which closely simulates field conditions with precision and ...

Loss of Control Prediction for Motorcycles during Emergency Braking Maneuvers Using a Supervised Learning Algorithm

open access: yesApplied Sciences, 2020
The most common evasive maneuver among motorcycle riders and one of the most complicated to perform in emergency situations is braking. Because of the inherent instability of motorcycles, motorcycle crashes are frequently caused by loss of control ...

Disc formation in turbulent cloud cores: Circumventing the magnetic braking catastrophe

open access: yes, 2012
We present collapse simulations of strongly magnetised, 100 M_sun, turbulent cloud cores. Around the protostars formed during the collapse Keplerian discs with typical sizes of up to 100 AU build up in contrast to previous simulations neglecting ...
