Existence and Hardness of Conveyor Belts [PDF]
The Electronic Journal of Combinatorics, 2020 An open problem of Manuel Abellanas asks whether every set of disjoint closed unit disks in the plane can be connected by a conveyor belt, which means a tight simple closed curve that touches the boundary of each disk, possibly multiple times. We prove three main results: For unit disks whose centers are both $x$-monotone and $y$-monotone, or whose ...

Chaos on the conveyor belt [PDF]
Physical Review E, 2013 The dynamics of a spring-block train placed on a moving conveyor belt is investigated both by simple experiments and computer simulations. The first block is connected by spring to an external static point, and due to the dragging effect of the belt the blocks undergo complex stick-slip dynamics.

Transport Performance of a Steeply Situated Belt Conveyor
Energies, 2021 The paper presents a methodology for determining the volume of a batch of conveyed material located before a transverse partition of a certain height and the distance over which the batch of material extends on the working surface of the conveyor belt ...

Determination of the limiting angle of inclination of tubular belt conveyor [PDF]
E3S Web of Conferences, 2020 Currently, the widespread use of tubular belt conveyors is constrained by insufficient justification of the conveyor parameters. In the work, on the basis of the theory of the limiting equilibrium state of bulk load, equations of equilibrium of load on ...
