plotting FRF - different direction

Recommended Posts

Hello together,

 

I am calculating modal frequency response analysis. At the end I would like to plot FRFs, i.e., the acceleration with respect to the applied force. When defining the direction of the acceleration, I can use just magnitude in the x, y or z. How can I define my own direction? 

 

Thank you for your help!
Matej

Hi Matej,


 


Do you mean the Y axis component for your XY plot?


 


If your results are in negative direction, HG will plot automatically in the negative coordinates.

I pick the "build graphs" botton. For "X type" I choose Frequency, for "Y type" acceleration. Then I have to choose "Y request", which is the node where I want to investigate the acceleration. Further, the "Y component" has to be defined. Magnitude and phase in all three direction are available. 


What I am asking is, how to define "Y component" in different direction than just X, Y and Z. I would like to have the component perpendicular to the surface of my part, since the acceleration is the maximum there.
