AISICO is able to offer computational mechanic services through finite elementi numerical modelling of dynamic phenomena, in accordance with regulation UNI CEN TR 16303:2020.<\/p>\n\n\n\n

The simulations certified by Aisico, applied to vehicular collisions, terminate with the evaluations of the behavior of the road restrain devices, already tested, in order to validate successive product alterations per regulation 1317-5:2012.<\/p>\n\n\n\n

2010:<\/strong> Start of FEM Numerical Simulations activity.<\/p>\n<\/blockquote>\n\n\n\n

\n

2018:<\/strong> AISICO is the first in Europe to obtain the UNI CEI EN ISO\/IEC 17025 accreditation for Numerical Simulations according to the standard (ex Pr EN16303:2018 now UNI EN 16303:2020)<\/p>\n<\/blockquote>\n\n\n\n

The technical team at Aisico provides a complete service, which encompasses the elaboration of complex 3D graphics and the modelling of the devices to be simulated, the calibration of the numerical model with the crash test on a real scale, and the numerical simulation through FEM software.<\/p>\n\n\n\n
