Mechanical Property Comparison of Al11Si Wheels Grain Refined by Ti, Nb and MTS [PDF]

Archives of Foundry Engineering, 2022
In this work, 25 wheels were cast with three different grain refiners: Al5Ti1B, Al3Nb1B and MTS 1582. Samples were machined from the wheels to check the mechanical properties.

Resistance Characteristics and Improvement of a Pump-Jet Propelled Wheeled Amphibious Vehicle

Journal of Marine Science and Engineering, 2022
Pump-jets have a relatively high propulsion efficiency at medium speed and in heavy-load conditions for wheeled amphibious vehicles. However, the geometry of amphibious vehicles is very special due to the installation requirements of the pump-jet, which ...

Forcing the Wheel

Order, 2023
Abstract Over the past 10 years, there has been considerable interest in exploring questions connecting dimension for posets with graph theoretic properties of their cover graphs and order diagrams, especially with the concepts of planarity and treewidth.

Numerical Investigation of the Influence of Tire Deformation and Vehicle Ride Height on the Aerodynamics of Passenger Cars

Fluids, 2022
Wheels and wheel houses contribute up to 25% of the total aerodynamic drag of passenger cars and interact in a complex way with their surroundings. Rims and tires induce complex flow separation mechanisms in a highly unsteady regime and the proximity to ...

Rectilinear car motions taking into account the elasticity and deformability of tires [PDF]

E3S Web of Conferences, 2023
In this paper, the problem of developing a mathematical model of rectilinear motion of a car is solved, taking into account the elasticity and deformability of tires, as well as, for the same radii of the wheels of the car, and taking into account plane ...

Analysis of factors affecting steering performance of wheeled skid-steered vehicles

The Journal of Engineering, 2020
Wheeled skid-steered vehicles have the advantages of compact structure, small steering radius and wide application. However, poor steering performance is an important limitation restricting the development of wheeled skid-steered vehicles.
