Nelineārā dinamiskā analīze¶
Šajā analīzē tiek izmantoti tutorial/13_dynamic_beam_nonlinear dati.
Analīzes objekts¶
Analīzes objekts ir tā pati konsolsija kā iepriekšējās sadaļas lineārajā dinamiskajā analīzē.

Analīzes saturs¶
Nelineārā dinamiskā analīze tiek veikta, ierobežojot 4.12.1. attēlā parādītās nostiprinātās virsmas pārvietojumu un slodzes mezgliem pieliekot koncentrētu slodzi. Analīzes vadības dati ir parādīti tālāk.

Analīzes rezultāti¶
Analīzes vadības datos norādītā novērošanas mezgla (slodzes mezgls, mezgla numurs 3121) pārvietojuma laika rinda, kas izveidota ar Microsoft Excel, ir parādīta 4.13.1. attēlā. Tālāk kā analīzes rezultātu skaitliskie dati ir parādīta daļa no novērošanas mezgla pārvietojuma izvades faila (dyna_disp_3121.txt).
