## dynamical behavier of weight-added Post Mod beam

## dynamical behavier of weight-added Post Mod beam

(OP)

Hi All,

On a modified beam I have statically proved that is OK. However on the beefed portion of the beam, since the weight of the Post-Mod beam is bigger than the original Pre-Mod beam, I was wondering what would be the dynamical behavior of the beam. I am thinking of getting approach to undamped natural frequency and somehow to prove it is against the resonance?

Thanks in advance for your opinions,

you can always do a modal analysis (FEA) of the mod'd beam.

possibly there's something novel in the loading ??

did someone ask you "what about dynamic response ?" or are you thinking about what could be an issue ?

how has your company written up this kind of work in the past ?

is this beam supporting an antenna ?
