This thesis revisits the concept of ground vehicles active suspensions system from a power harvesting perspective. I introduce the two dimensions of freedom quarter vehicle model for calculations of vehicle dynamics as well as a road profile model based on PSD classifications based on International Organization for Standardization’s technical document, ISO 8608 “Mechanical vibration -- Road surface profiles -- Reporting of measured data”. I report the power harvesting potential of the conventional viscous fluid dampers for an extensive range of road profile roughness indices and vehicle speeds. I explain the problem of additional power harvesting from the regenerative electric damper operating in the "dead-zone" and introduce Pulse Width Modulated (PWM) DC-DC converter as a solution. I analyze the efficiency of this system by circuit level simulations in PSpice. / Graduate / 0540 / 0544 / farhang@uvic.ca
