Abstract

Suspension dampers have played a significant role in the automobile industry for years and are a crucial part of the modern-day commute. For years now, the viscous passive damper has been dominant. However, with the improvement of vehicle performance and unpleasant road conditions, there is a constant need to improve and revolutionize the damping technology. Controlled shock absorbers capable of adapting on uneven road profiles are required to meet this challenge and improve the passenger comfort level. Among the many types of modern damping solutions, Magnetorheological Dampers (MR) based dampers have gained significant attention from researchers considering their damping force control capability, fast adjustable response, and low energy consumption. The MR damper consists of magnetic particles suspended in a viscous liquid whose rheological properties can be altered with the application of an external magnetic field. MR dampers fall into the category of semi-active damping systems, which require external energy to alter the magnetic field and excite the suspended magnetic particles, thereby improving the vibration damping. Advancements in energy harvesting technologies provide an option to regenerate a portion of energy dissipated in automotive dampers. While the amount of regenerated energy is often insufficient for regular automobiles, it could prove to be vital for improving the performance of lightweight battery-operated vehicles. In battery-operated vehicles, this regenerated energy can be used for powering several secondary systems, including lighting, heating, and air conditioning, and so on. The goal of this project is to design a hybrid smart suspension system that combines the MR damping technology along with an electromagnetic induction (EMI) based energy harvesting system for applications in lightweight personal vehicles. The project involves extensive designing, numerical simulation, fabrication, and testing of the proposed smart suspension system. The development of the proposed damping system would help advance harvesting of clean energy and enhance the performance and affordability of future personal vehicles.
