simply supported beam

simply supported beam

simply supported beam

(OP)
My final year engineering project involves study of vibrations in beams.
how do subject a simply supported beam to vibrations without causing it to fly out of control?

RE: simply supported beam

Why would it fly out of control???

RE: simply supported beam

Unless you excite at a natural Feq

RE: simply supported beam

It won't fly out of control, in practice, even at resonance, since your excitation method is not a truly linear system.

Would you like to describe your setup as you currently envisage it? and details of the test specimen, and, what I'm dying to hear, how you made a pin joint?



Cheers

RE: simply supported beam

Use a very small level of excitation is the obvious answer.

RE: simply supported beam

My answer was given in the way that it was because I didn't think the above poster really knew what simply supported BC meant..the way he described the stituation it sounded as if he thought simply supported meant no restriction on the deflection at the simply supported end.........and as Greg alluded to if he really knew what it was then he would know that getting such a BC is not the easiest thing in the world to so in the lab....
