Dynamic analysis of a Component

Recommended Posts

Hello,


 


I want to know the procedure for performing the dynamic analysis of a component using the optistruct.


 


The following are the conditions.


 


1.    50-500 hz frequency


2.    15g acceleration.


 


 


Can you please let me know know how to perform the analysis.


 


 


Regards,


 


Rajesh.

Hi Rajesh,


 


Please refer to the below tutorials:



OS-1300: Direct Frequency Response Analysis of a Flat Plate

 



OS-1305: Modal Frequency Response Analysis of a Flat Plate

Hi,


 


Please find attached Direct Frf tutorial using Optistrcut solver.


Instead of DAREA create a unit load in a particular direction of type SPCD. 


 


Under RLOAD refer the Spcd load collector for exciteid and the last field on RLOAD can be changed to ACCE.

Hi Shreerang,

Both SPCD and DAREA are the load type cards used to represent a dynamic excitation.

DAREA is used to represent simple point forces / loads, which is then flagged with a table to represent time / frequency history.

SPCD is used to represent enforced / base excitations (enforcing a node/s) with Displacement, Velocity or Accelerations which are then acted upon by a table to represent time/ frequency history.
