Abstract:
The study of dynamical performance and effectiveness of developed Vibration Energy Harvesters based on Electromagnetic Tuned Mass Dampers applicable for Hybrid Automobiles is presented. The composed Vibration Energy Harvesters consists of two main components: regular Tuned Mass Damper and Generator of Electrical Signals. The invented Vibration Energy Harvester could be fabricated in two main versions: for rectilinear vibration applications and for angular rotational applications. The considered Vibration Energy Harvesters are used successfully for equipping of driving sources: internal combustion engine and electric motors interconnected by means of special gearing. The presented solutions demonstrate high efficiency and would be applied for a design in all kinds of Hybrid Cars. The structural analysis of invented schemes shows some perspective features and directions for design. Specific particularities and control properties are provided for explanation of effectiveness of Vibration Energy Harvester operation. Mathematical model dynamics describing the interconnected mechanical and electromagnetic solutions of developed Vibration Energy Harvester is analyzed. Practical applications of Vibration Energy Harvesters for 18 kW Free-Piston Linear Internal Combustion Engine linked to Electrical Generator equipped by Additional Auxiliary Drive and for 1.9 L Diesel Engine were tested. Test results illustrate the efficiency of proposed Vibration Energy Harvester and some new opportunities for their applications.
