Frequency response analysis - settings

Recommended Posts

Hello, I am writing to ask how correctly set FRA analysis?
I've made an example with simple plate:
1.Modal analysis:

2. FRA analysis:
- frequency function like that (just for example)


- base excitation - acceleration

3. Result:

Result isn't the same as in modal analysis as I supposed to. I expected peak values in 26Hz, 116Hz, 169Hz where resonace will occur.

Somewhere I made a mistake, can anyone help me?
