Vibration testing - Import export

This quarter-turn lock is vibration-resistant through a detent mechanism in the end position. Right or left mounting with 90° closing and internal rotation limit. The quarter-turn lock can be installed pre-assembled (limitations by small A-dimensions and thick doors). Tested according to DIN EN 60068-2-64 (vibration) and DIN EN 60068-2-27 (shock), test standard 61373. Vibration-proof as per rail applications category 1, class B requirements (highest requirement). Water and dust proof as per IP65 through O-ring and flat seal. Order the required tongue version separately. Every tongue can be combined with every housing. Accessory: Lock key 05586 Drawing reference: Actuation: a) square 6 mm b) slot c) triangle 6,5 mm

EVED series elastomeric visco-elastic dampers consist of one or more layers of high-damping elastomeric mixture, characterized by equivalent viscous damping 15÷20% and shear deformation of 100%. Traditionally they are used as components of dissipative bracings in buildings in a framework; the layers of elastomer can be arranged both on the vertical and horizontal plane. Experimental hysteretic cycles of an EVED damper (frequency 0.5 Hz and shear deformation ± 100 %). Vibrating table tests on a concrete frame with EVED dampers on top of a reverse-V bracing. An EVED damper installed at the Gentile-Fermi school of Fabriano.

Shape-memory alloy devices SMAD are axial restraining devices that exploit the superelastic properties of shape-memory alloys. The force-displacement curve, characterized by one or more "wedges" (sections where force remains nearly constant while displacement increases), allows SMAD to limit the maximum force transferred to the structure they are connected to. They are also characterized by a significant recentering capacity. Experimental force-displacement curve of a shape-memory alloy device. Vibrating table tests on brick walls with SMAD devices used as horizontal tie rods. SMAD devices installed at the San Francesco Basilica in Assisi.

LRB isolators are elastomeric isolators with a cylindrical-shaped core of lead. The plasticization of lead permits to obtain an equivalent viscous damping coefficient up to approximately 30%. The constitutive bond of LRB isolators is bilinear; for design purposes it is possible to use equivalent non-linear or linear models, according to regulatory provisions. Experimental hysteretic cycles of an LRB isolator at a 0.5 Hz frequency and cutting deformation ± 100%. Vibrating table tests on an LRB isolator at the National Technical University of Athens (Greece). LRB isolators installed in the office building "La Torre" of Ancona.
