Vehicle Dynamic Analysis for the Ball-Screw Type Energy Harvesting Damper System

摘要

The number of electronic components in modern vehicle chassis systems has been increasing, and energy harvesting systems are one of the main parts. Energy harvesting dampers have been developed to improve the energy efficiency, and in this paper, a ball-screw type energy harvesting damper system is modeled, and the dynamic characteristics of the system are analyzed. A quarter-car model is used to simulate the energy harvesting damper system. A comparison of the experimental and simulation results reveals that the ball-screw energy harvesting damper system modeling is adequate to develop a ball-screw energy harvesting damper system based on 48 V power system.
