Vibration Energy Harvesting Damper in Vehicle Driveline 2019-01-0782

The vibration mitigation could provide mutually interconnected results: reduction of undesired vibration levels and generating of additional electrical power. New Vibration Energy Harvesting Damper (VEHD) schematically based on author’s US Patent 7,464,800 and consists of two main components: Tuned Mass Damper and Generator of Electricity. The analysis of dynamical performance and effectiveness of developed VEHD applicable for all types of Automotive is presented. The invented VEHD could be fabricated in two main versions: for rectilinear vibration applications and for angular rotational applications and should be integrated in driveline. Mathematical model of dynamical behavior is developed. An example of automatic transmission 545 RFE is considered for simulation analysis. The structural study of invented schemes shows some perspective features and directions for design. Specific particularities and control properties are provided for explanation of effectiveness of VEHD operation. Test results illustrate the compliance with theoretical predictions, efficiency of proposed VEHD and some new opportunities for their applications.
