Mathematical Model Shaker
Mathematical Model Shaker
(OP)
Hi all!
I have the great pleasure to build a mathematical model of my Ling Dynamics Shaker v406.
Can anyone provide me a finished model? I already know that the shaker works such as a loudspeaker with series impedance (Rs+Ls) and a mechanical parallel RLC system. But
1) How can I find out the parameter: L(series), stiffness, damping? I have already build a model with MATLAB but the parameter do not match to the results.
2) Can anyone give me good literature sources? It is difficult to get appropriate information about shakers!
Thanks a lot!!
