Vibrations of a folded plate
— In this article, it is shown that the eigenvalues and eigenvector s o f the threedimensional linearized elasticity operator in a thin folded plate converge toward the eigenvalues and eigenvectors of a limit 2d-2d model as the thickness o fthe plates tends to 0. The convergence o f the associated stresses is also established. Resumé. — On montre dans cet article que les valeurs propres et vect...
متن کاملORIGAMI – Folded Plate Structures, Architecture
This research proposes new methods to generate rapidly complex folded plate structures that can be built with cross laminated timber panels. Composition and dimensions of these panels as well as the possibility to mill them by Computer Numerically Controlled machines, show a great potential for surface structures. The aim of this research is to reveal this potential in the domain of folded plat...
متن کاملCurved Folded Plate Timber Structures
Current research at the laboratory for timber construction IBOIS at EPFL focuses on shell structures. Two main families are investigated: shells made of linear elements, as timber rib shells, and shells made of surface elements, typically folded plate structures. With regard to timber rib shells, bent linear timber elements are used to create the shape of a shell. With folded plate structures, ...
متن کاملA New Approach to the Study of Transverse Vibrations of a Rectangular Plate Having a Circular Central Hole
In this study, the analysis of transverse vibrations of rectangular plate with circular central hole with different boundary conditions is studied and the natural frequencies and natural modes of a rectangular plate with circular hole have been obtained. To solve the problem, it is necessary to use both Cartesian and polar coordinate system. The complexity of the method is to apply an appropria...
متن کاملSensorless manipulation using transverse vibrations of a plate
The existing industrial parts feeders move the parts through a sequence of mechanical lters that reject parts in unwanted orientations. In this paper we develop a new apparatus that uses a novel vibratory mechanism to systematically manipulate parts, by actively orienting and localizing them. These new automation designs promise great exibility, speed, and dexterity| we believe they may be empl...
