Automotive Wheel Rim using Carbon Reinforced Composite Material – Finite Element Analysis and Investigation
Main Article Content
Abstract
The oil crises in early 1970’s draw the attention of researchers to explore alternate option to reduce the dependence on fossil fuels for transportation. This trend derived the possibility of electric vehicles (EVs) powered by batteries. The two main challenges, currently, these EVs are facing are long charging time to charge the batteries and limited range. This work deals with the solution of reducing weight to address the above mentioned two challenges. A carbon reinforced composite (CRC) is used to replace the usual alloy material in the fabrication of vehicle wheels. Finite Element Analysis (FEA) has been used to study the structural properties under usual loading conditions. The results proved that the use of CRC for wheel rim can reduce the weight of unsprung mass of the vehicle and also rotational inertia of the wheel assembly. This reduction in weight can help improve the life of battery installed on the EV. Thus, improving the endurance and range of EV.
