Bulldozer Blade Optimization Design Based on Joint Simulation Technology of RecurDyn and EDEM

Shock and Vibration, Volume 2025, Issue 1, 2025.
With the intensification of global environmental issues, the pressure on construction machinery to reduce energy consumption and emissions has been steadily increasing. As a critical component of construction machinery, bulldozers, characterized by high emissions and fuel consumption, have garnered significant attention.

A Study of the Controlled Motion of a Four-wheeled Mecanum Platform [PDF]

Nelineinaya Dinamika, 2018
Summary: The object of the study is the mobile platform of the KUKA youBot robot equipped with four Mecanum wheels. The ideal conditions for the point contact of the wheels and the floor are considered. It is assumed that the rollers of each Mecanum wheel move without slipping and the center of the wheel, the center of the roller axis, and the point of

Observer‐based finite‐time time‐varying elliptical formation control of a group mobile mecanum‐wheeled omnidirectional vehicles for collaborative wildfire monitoring

IET Control Theory &Applications, Volume 18, Issue 13, Page 1669-1685, September 2024.
In an effort to reduce damage and accidents during wildfire combat, this article proposes a control scheme for a group of mobile mecanum‐wheeled omnidirectional vehicles (MWOVs) assigned to monitor wildfire spread. The control scheme guarantees fast finite‐time convergence of cooperative tracking errors, even in the presence of unknown external ...

Geometry, kinematics and dynamics of the Mecanum wheel. Unstable motion of the Mecanum vehicle

Izvestiya MGTU MAMI
BACKGROUND: The Mecanum wheels enable the vehicle to move in any desired direction and increase its mobility when moving along a flat surface. When designing a vehicle, the design loads determine the required driving moments and, as a result, the characteristics of the drivetrain.
