The road roughness is one of the main sources of a severe undesired vehicle vibration. The vehicle suspensions are the front lines of defense protecting the passengers and vehicle equipment from harsh vibrations caused by the ground road roughness. The recent tendency is to combine the process of vibration mitigation and additional electrical power generation. It allows scavenge the power from a vehicle’s vibrations and convert these vibrations into electrical power for use in vehicle systems. New Vibration Energy Harvesting Damper (VEHD) is based on author’s US Patents and consists of two main components: Tuned Mass Damper with automatic self-tuning properties and Generator of Electricity. The analysis of dynamical performance and effectiveness of developed rectilinear VEHD for Jeep Sport Wrangler vehicle suspensions is presented.

The rural off-road exploiting of amphibious all-terrain vehicles leads to the intensive vibrations of all parts of a vehicle, and specifically of its chassis. The tested amphibian vehicle’s chassis has the lowest natural frequency of 19.34 Hz. The Vibration Energy Harvesting Damper (VEHD) is used for mitigation of chassis vibrations. VEHD provides the mutually interconnected results: a reduction of undesired vibration levels and a generating of the additional electrical power. Newly patented VEHD consists of two main components: Tuned Mass Damper and Generator of Electricity. The perspective feature of proposed VEHD is the ability of effective vibration damping in a broad range of frequencies due to implementation of a control device, while that device is keeping automatically the changing natural frequency of VEHD equals to current frequency of the external force. The mathematical simulation analysis based on parameters of the amphibious all-terrain vehicle chassis is developed.

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 Automotives 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 behaviour 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.
