Abstract

For the prevention of environmental pollution, there have been many researches which are eco-friendly vehicles in the automobile industry. In this paper, we studied for the non-pneumatic tires(NPT)can increase fuel consumption compared to conventional pneumatic tires. On driving, energy loss of tires occur when tires impact an obstacle on the road. This energy loss directly is relate to the fuel efficiency. Therefore, the energy loss of non-pneumatic tires is compared before and after impact. In this study, the results of energy loss of non-pneumatic tires and pneumatic tires was compared, when tires are rolled over an obstacle. As a result, the energy loss of non-pneumatic tires was less than pneumatic tires. This researches were performed the ABAQUS using finite element method and obtained the difference of velocity and kinetic energy from the program.
