Electronic Regenerative Shock Absorber (ERSA) is a vibration energy harvesting mechanism in vehicles in which the relative motion of the vehicle body to the road is transformed into a source of electrical energy using the concept of a linear generator. Additionally, the performance of the previous ERSA mechanism has been still relatively low, and it has been only able to produce electrical energy generation of 0.8 V. This has been affected by the number of coils, the diameter of the wire and the air gap magnet. In this study, the optimization of the three variables above has been carried out using the Taguchi method. Actually, each variable has consisted of three variations. Factor A (number of coils): 1000, 1500, 2000, factor B (wire diameter): 0.2 mm, 0.3 mm, 0.4 mm and factor C (air gap) 2 mm, 4 mm, 6 mm. From all the factors, nine levels of orthogonal arrays have been formed. Based on the stages undergone in the Taguchi method, the best ERSA configuration has been obtained with the configuration of factor A (number of coils): 2000 coils, factor B (wire diameter): 0.3 mm and factor C (air gap): 0.4 mm. Hence, the optimization data obtained can be used as a reference for future ERSA development. © 2021 Praise Worthy Prize S.r.l. - All rights reserved.
