Multiple Cantilever Beams
Multiple Cantilever Beams
(OP)
I have a situation where I have centrifigal blower being supported by three structural beams that are cantilevered to a certain distance. I need to find the natural frequency of the system so that I can check to make sure that the blower does not run at that same frequecy. How do I calculated the natural frequency of all the beams?
Anyones input would be appreciated.
Thank you, Mike

f=1/(2*pi)*sqrt(k/m)
f is in Hz, all the other units need to be correct.
If this is in the ballpark of your running speed then go and look Blevins up, or do an FE model.
