Study of the Influence of the Two-Drive-Axle Bogie Parameters on the Three-Axle Vehicle Handling

Machines
The presence of a bogie in three-axle vehicles when moving along a curved trajectory leads to deterioration in its handling and maneuverability. The paper developed a mathematical model of the elastic bogie wheel while moving along a curvilinear ...

Efficient and Adaptive Autonomous Guidance and Control of Planetary Rover With Improved Traction Controller and Dynamic Cost Map

Journal of Field Robotics, EarlyView.
ABSTRACT Planetary exploration is rapidly gaining importance within the space research community. Autonomous locomotion of rovers requires consideration of several mobility aspects to ensure safety, including avoiding hazardous areas that can cause the robot to become immobilized in soft soil or damaged in sharp terrains.

Dynamic of Friction Coupling Independently Rotating Wheels for High Speed

Shock and Vibration, 2017
A new lateral coupling structure with independently rotating wheels (IRW) is proposed, and longitudinal creepage is obtained by replacing the gear pair with the friction pair to synchronize the rotation speed of left and right wheels.

Dynanics of a vehicle-track coupling system at a rail joint [PDF]

, 2015
The dynamic behaviour at a rail joint is examined using a two-dimensional vehicle–track coupling model. The track system is described as a finite-length beam resting on a double-layer discrete viscous-elastic foundation.

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges

Structural Concrete, EarlyView.
Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

A study of lateral-force estimation equation focusing on moment of a train bogie

Nihon Kikai Gakkai ronbunshu, 2016
When railway vehicles pass through a sharp curve, yaw moment is generated at the bogie. This condition affects the increase of the lateral force of the outside wheel of the front axle of the leading bogie, which is important factor for assessing the ...

Articulated suspension system [PDF]

, 1989
The invention provides a rough terrain vehicle which maintains a substantially constant weight, and therefore traction, on all wheels, despite one wheel moving considerably higher or lower than the others, while avoiding a very soft spring suspension ...

The Venetian Vernacular Lexicon in Eleventh‐ and Twelfth‐Century Latin Documents: Insights from the Codice Diplomatico Veneziano

Transactions of the Philological Society, EarlyView.
Abstract This study investigates the lexicographical potential of Medieval Latin documentation from the Venetian area of the Italo‐Romance domain, highlighting the need for a systematic approach to bridge Latin and vernacular linguistic developments. The project MEDITA – Medieval Latin Documentation and Digital Italo‐Romance Lexicography.
