Abstract
The design of a simple electromechanical system which is dynamically equivalent to an active vibratory system is studied in this paper. A two-step process is presented in which a passive vibratory system is first obtained, which is then modified in the second step to achieve active equivalence. Implementation of the active emulation step is achieved by closed-loop control of electromechanical shakers attached to the passive system and driven so as to generate the appropriate vibrations at the mounting locations of the active vibratory system. Experimental examples are used to demonstrate the effectiveness of this design process.
