Analysis of scattering operation for wheel loader considering digging behaviour of soil

open access: yesNihon Kikai Gakkai ronbunshu, 2020
This paper presents a dynamics simulation technique of the scattering operation for the wheel loader taking into consideration of both digging the soil and travelling on the soil, in which the multibody dynamics analysis is coupled with the Discreate ...

Stair‐Climbing Wheelchairs for Enhanced Mobility: A Comprehensive Review of Fundamental Mechanisms, Design Concepts, and Performance Analysis

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT People with physical disabilities face significant mobility challenges while climbing uneven surfaces and staircases. In these circumstances, traditional wheelchairs do not provide stable, safely controlled mobility, underscoring the importance of building superior stair‐climbing wheelchairs for both medical and infrastructure purposes.

Application and Experimental Validation of a Multibody Model with Weakly Coupled Lateral and Vertical Dynamics to a Scaled Railway Vehicle

open access: yesSensors, 2020
In this paper, a multibody dynamic model of a railway vehicle that assumes that vertical and lateral dynamics are weakly coupled, has been experimentally validated using an instrumented scaled vehicle running on a 5-inch-wide experimental track.

Hexapod Locomotion Across Structured and Unstructured Terrains: A Data‐Driven Review of Modeling, Control, and Validation

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The design of a hexapod is complex and requires integration between kinematic models, control systems, and sensing. Existing literature has reviewed these sub‐systems in isolation. Since 2021, there has been no review of the field despite significant advancements in soft soil, lunar traversal, and artificial intelligence.

Dynamics Study of Straddle-Type Monorail Vehicle With Single-Axle Bogies-Based Full-Scale Rigid-Flexible Coupling Dynamic Model

open access: yesIEEE Access, 2019
The longitudinal drawbar and the lateral stabilizer bar of straddle-type monorail vehicle with the single-axle bogies have relatively long structure size. The multibar system leads to deformation during the driving process due to impact loads, even leads

Unraveling authoritarian reform decision‐making: A metacognitive–subcognitive model

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Recent research indicates that state reforms in East and Southeast Asia have been predominantly top‐down and authoritarian‐led. However, this significant observation implicitly relies on important assumptions about authoritarian decision‐making behavior and psychology that remains understudied.

Standing on a common ground: a comparison of static stability approaches for pallet loading

open access: yesInternational Transactions in Operational Research, Volume 34, Issue 1, Page 501-527, January 2027.
Abstract At the practical level, the static stability constraint is one of the most important constraints in practical pallet loading problems, such as air cargo palletizing. Approaches to modeling static stability, which range from base support and mechanical equilibrium calculations to physical simulation, differ in workflow, focus, and assumptions ...

Analysis of servo-constraint problems for underactuated multibody systems [PDF]

open access: yesMechanical Sciences, 2013
Underactuated multibody systems have fewer control inputs than degrees of freedom. In trajectory tracking control of such systems an accurate and efficient feedforward control is often necessary.
