【 摘 要 】

His investigation is aimed at exploring the possibility of energy recovery through the suppression of vibrations. The article describes a new type of regenerative suspension using electromagnetic tuned mass damper (TMD) approach. The magnetic part of the device performs the function of the TMD, thereby providing both energy regeneration, and damping properties to the protected structure. Equations of optimal parameters of TMD, such as stiffness and damping coefficient were obtained according to the theory of TMD. Then, optimized TMD was mounted in structure with characteristics typically for car wheel. Therefore, efficiency of using TMD for such structures was revealed by amplitude and acceleration frequency response plot. Equation of velocity of TMD was obtained as well. Further estimated regenerative function of current TMD system was investigated: electromotive force for one coil equals to 0.03V, at 1.13 m/s TMD velocity. Finally, the aims of the further research were determined as well.
