Vsebina analize¶
Linearna dinamična analiza se izvede tako, da se omejijo pomiki vpete ploskve, prikazane na sliki 4.12.1, ter na obremenitvena vozlišča deluje koncentrirana obremenitev. Podatki za krmiljenje analize so prikazani spodaj.

Rezultati analize¶
Slika 4.12.3 prikazuje časovni potek pomika nadzornega vozlišča (obremenitveno vozlišče 3121), določenega v krmilnih podatkih analize, izdelan z Microsoft Excelom. Del izhodne datoteke pomika nadzornega vozlišča (dyna_disp_3121.txt) je spodaj prikazan kot numerični podatek rezultatov analize.
