Question pipe vibration caused by inflow

sherry0fly is on a distinguished road
I am trying to bulid a model which described air flow fast though the 'U' pipe and cause the vibration of pipe (transient).
what I have done is I use FSI with system coupling.
Now I have obtained the transient results of pressure on the pipe inner wall.
But I dont know how to simulate the vibration of the pipe.
Is there anyone modeled the similar case and could help me?

By the way, I learned to build acoustics model.
I m just considering if the FLUENT can work out the sound level, it should also can work out the frequency of vibration.
But how?
