Abstract :
Vibrational vehicles energy is usually dissipated by the suspension hydraulic shock absorbers. During the last two decades, researchers began looking into harvesting the vibrational energy using various magnetic devices. In the present paper the major achievements of this research are reviewed. The theoretical framework for the design of permanent magnet linear synchronous generators (PMLSG) used as vehicle suspension dampers is outlined. An original experimental device is developed. The optimum size and configuration of the device are derived using finite element (FE) analysis. Materials and technical solutions are chosen analyzing previous experimental studies. The most important feature of the device is the versatile structure which allows the study of various machine topologies. Electro-mechanic and thermal characteristics are numerically and experimentally investigated.
