Sommario

Viene presentato un approccio cineto-elasto-dinamico, basato su tecniche agli elementi finiti, per meccanismi piani ad 1 g.d.l. Nessuna ipotesi è richiesta per la legge del moto del meccanismo di riferimento a membri rigidi. Detta legge del moto è calcolata in maniera dinamica diretta. Un semplice caso di prova mostra l'indipendenza della risposta dalla scelta del meccanismo di riferimento. Il contenuto in frequenza della risposta corrisponde alle frequenze prevedibili per il modello.

Summary

A Kineto-Elasto-Dynamic approach, which is based on the use of finite elements, is presented for 1 d.o.f. planar mechanisms. No requirements are needed for the reference rigid mechanism time-history, which is computed in a fully dynamic way.

A simple test case shows the independence of the response from the chosen reference mechanism.

The frequency content of the response matches the expected frequencies of the model.
