About Braking of Wheeled Vehicle Equipped with Automated Brake Control System
Наука и техника, 2022 The paper proposes a method for determining a vehicle stopping distance based on a braking rate and a coefficient of using an adhesion force by an automated control system for regulating a braking force on the example of a multi-axle vehicle.

Wheels on Wheels on Wheels—Surprising Symmetry
Mathematics Magazine, 1996 I was thinking of the curve traced by a particle on a wheel mounted on a wheel mounted on a wheel, each turning at a different rate. The first term represents the largest wheel, of radius 1, turning counter-clockwise at one radian per second. The second term represents a smaller wheel centered at the edge of the first, turning 7 times as fast.

Size effects on free vibration of heterogeneous beams
MATEC Web of Conferences, 2018 In this paper the influence of microstructure on the free vibration of geometrically similar heterogeneous beams with free-free boundary conditions was numerically investigated by detailed finite element analysis (FEA) to identify and quantify any effect

On the metric basis in wheels with consecutive missing spokes
AIMS Mathematics, 2020 If $G$ is a connected graph, the $distance$ $d(u, v)$ between two vertices $u, v \in V(G)$ is the length of a shortest path between them. Let $W = \{w_1,w_2, \dots ,w_k\}$ be an ordered set of vertices of $G$ and let $v$ be a vertex of $G$.

Coupled 3-D full-Stokes modelling of tidewater glaciers
Annals of Glaciology, 2022 Tidewater glaciers are an important and difficult part of the cryosphere to study owing to their complex nature and often inaccessible and physically challenging environments. The interaction of glacier and fjord processes furthermore presents particular

Failure Analysis of ICE Cylinder Units and Technology for Their Elimination
EngThe mechanisms of in-service damage caused to the cylinder units of internal combustion engines (ICE) during their operation are analyzed. Long-term operation under harsh conditions, failure to comply with operating conditions, and breach of design and ...

Journal of the American Chemical Society, 1996 A simple method to prepare porphyrin 'wheels' on a micrometer scale is described. It is possible to arrange several types of porphyrin derivatives, including Protoporphyrin IX and Chlorophyll-a, in the form of rings using this method. A mechanism for the formation of these types of assemblies is proposed that is based on the generation of '2D-gas ...

Shape optimisation of rim structure of aluminium alloy car wheels based on 90° impact test
Scientific ReportsAutomotive wheels are critical components for vehicular safety, with the rim subjected primarily to radial bending loads during operation. Balancing rim thickness and structural integrity under these loading conditions is imperative.
