Meta-Model Based Blade Optimization Design Considering the Fluid Characteristics of Vehicle Energy Harvesting

The advancement of transportation machinery has played a crucial role in driving global economic and societal growth. However, this progress has also given rise to challenges, such as the depletion of chemical resources and the escalating impact of climate change. As a result, automobile companies are now prioritizing energy efficiency and transitioning towards eco-friendly vehicles. In response to this demand, various efforts have been made to harvest energy and improve the efficiency of eco-friendly vehicles, with energy-harvesting dampers emerging as a promising solution. This study focuses on the optimization of the shape and design of a rotary power generation system integrated within an energy harvesting system. The primary objective of the rotary power generation system is to convert mechanical motion into electrical energy, thereby enhancing the overall efficiency and sustainability of eco-friendly vehicles. By considering the specific characteristics of SAE 30 W working oil within the damper, the optimal blade shape and generator can be determined to maximize the power generation capabilities of the system.
