Hi all, 

I'm doing tutorial about FRF, and I have a question: what does the value in y - collumn represent for (in Excitation table - TABLED1)?

    Hi Nancy,

    In FRF analysis, TABLED1 curve is plotted for Load Vs frequency curve. You can apply load by creating SPCD (for Displacement, velocity & acceleration) or by DAREA (Force). This load gets multiplied with Tabled1 Y-axis value in RLOAD1/RLOAD2 which combines both (Excite id = SPCD/DAREA, TB =TABLED1). Hope this explains your doubt.

    Thanks
