can someone tell me about FRF graph which i've got from harmonic analysis result, especialy, what is the meaning of VALU (y-axis). Is that an Amplitude? Amplitude of what?
As an information, before solution begin, i only add range of frequency, without loading/excitation force. It pure by...
i've remake my model with the different scale. when i got a small natural frequency, i use milimeter. but in my new model i use meters. and the result natural frequency was increase. Is that true that scale of model affect the result for natural frequency?
And for additional information, my...
I've a problem with my analysis with modal. I made a model of locomotive car body, and i want to find out it mode shape and natural frequency. But i got a very weird result, this is my result
