La simulazione accurata delle manovre operative di veicoli industriali è fondamentale per ridurre i costi e i tempi associati alle attività sperimentali. In questo contesto, il miglioramento della capacità predittiva dei modelli multibody con corpi flessibili, in particolare per la stima dei carichi strutturali, riveste un ruolo chiave.
Il presente studio si concentra su un carrello elevatore...
Elastic wave control via mechanical metamaterials has attracted significant research interest, as these structures can exhibit unconventional dynamic properties, including phononic band gaps, arising primarily from their architecture rather than their constituent material.
Among the architectural strategies explored, fractal-based geometries, characterized by self-similarity and scale...
Objective
Hybrid electromagnetic suspension (HEMS) is a promising levitation architecture with reduced power consumption as permanent magnets (PMs) provide a passive force bias. It represents an enabler for commercial maglev system implementation. With levitation modules arranged in a transverse-flux (homopolar) configuration, less losses are provisioned with respect to a heteropolar...
Questo articolo affronta l'analisi del fenomeno sismico dello sloshing in un recipiente in pressione per applicazioni nucleari. Le distribuzioni di pressione impulsiva e convettiva vengono esaminate utilizzando le normative, basate su modelli meccanici semplificati, unitamente agli spettri di risposta sismica di piano (FRS). La dinamica dello sloshing viene approfondita mediante un modello di...
The design process of modern aeronautical engines requires the dynamic characterization and stress certification tests of critical components, such as the bladed disks forming the stages of compressor and turbine modules.
During these tests, the bladed disk is assembled into a spinning test rig where a predefined acceleration ramp is recreated simulating different operating conditions. In...
