Hey. I am trying to study the modal properties of cantilever beam. The experimental apparatus that I have include an electromagnetic shaker and a power amplifier. The beam under testing is clamped to the shaker at one end and is free at the other. I have theoretically calculated the displacement...
cheers folks.... Still confused though... The thing is I am exciting beams that are fixed at one end to the shaker. I can estimate the deflections induced in the beam and from that , I can calculate the effective load applied at the free end to cause that amount of deflection. However,I am...
Cheers for that. Yeah I figured that out, but my concern is how do I estimate the force exerted by the shaker? I mean I know the frequency of excitation of the shaker and the voltage of the power amplifier at that frequency but do not know how to determine the force.
Hi. I am using an electomagnetic shaker coupled to a power amplifier to excite rectangular aluminium beams at their first and second natural frequencies. I have estimated the deflections of the beam at each of the frequencies and know the mass and dimensions of the beams. I want to to know, if...
