Force results in MPC184 elements vs Frequency in Random Analysis

[nicolas.cuello]

Hi all.

I would like to know if there is some way to extract the forces vs frequency in a random analysis.

I have solved a modal analysis first in my model and I have found the resonance frequencies, then i solved a random analysis. Now, i want to know the forces in several bolts conections (modeled with a 1D beam + MPC) in function of the frequency to study which frequecies have most impact in the bolts conections.

Is there a way in ANSYS Workbench or with some command in APDL to extract this information?.

Thanks.

Nicolás.

You mention MPC184, but it sounds like you want results for an ordinary beam element.  If Mechanical is creating results for these elements (not a given), then you can use APDL commands like these:

/POST26 

ESOL,2,Element_Number,,SMISC,1 

RPSD,3,2  ! Force RPSD 

/SHOW,PNG 

PLVAR,3
