VIBRATION ISOLATION IN A THIN RECTANGULAR PLATE USING A LARGE NUMBER OF OPTIMALLY POSITIONED POINT MASSES

摘要: A new approach is presented for dealing with the problem of vibration control in a plate over moderately wide frequency band. The band interest does not contain first few eigenvalues, nor it restricted to very high frequencies, but typically contains five or six eigenfrequencies 10's eigennumber. idea make minor modifications structure which are sufficient change its response so that transmission vibrations given suppressed. This work illustrated by application rectangular carries 50 identical point masses variable positions. novel method selecting optimal mass position demonstrated and compared results positions determined Genetic Algorithm (G.A.).
