N2 - An adaptive electromechanical tuned vibration absorber (ETVA) is developed consisting of a voice coil and a single degree of freedom mass spring system. The natural frequency of the ETVA is varied and tuned by addition of a variable capacitor. In this paper, the design, mathematical model, and experimental data of the ETVA is presented. Experimental data indicates that the natural frequency of the ETVA can be varied by 66% using capacitive shunting of the voice coil. Analytical studies have also revealed that if the wires of the voice coil could be replaced with room temperature superconductors, the natural frequency of the ETVA can be changed by a factor of 8 using a resistive shunting of the voice coil. The ETVA is then used in conjunction with a passive fluid mount to create a variable notch semi active fluid mount. Finally, the mathematical model and simulation results of the ETVA plus the passive fluid mount are described and presented. Copyright
