Abstract

This paper aims to evaluate the energy consumption of motorcycle operating in urban traffic. Position, speed, and elevation in each time segment are collected by GPS - tracking data from the journey of motorcycle Honda Verza 150 in Bandung city. The distance, acceleration, and required tractive force for the motorcycle motion are then calculated. Furthermore, the energy consumption is investigated by modeling the motorcycle and calculating tractive force from the force equilibrium. For each time segment, engaged gear is then proposed for the best energy efficiency. The relationship among speed, required tractive force, and shifted gear according to time and distance are comprehensively discussed.

Abstract

The main challenging issues of vehicles with electric propulsion are on the limited energy source due to relatively low battery capacity and low excitation of power traction. They can be tackled down by designing lightweight structures for frameworks and bodies of the vehicles. Composite materials which have a high strength to weight ratio are the best choice for designing and manufacturing the lightweight structures. A review of recent progress in utilization of the composite materials for electric vehicle structures is presented. It focuses on how the structures can support the electric vehicles to compete with internal combustion engine vehicles regarding their performance on the road. The utilization of composite material for structures of railway vehicles is also summarized. Furthermore, discussions are extended to the key technologies required for applying the composite materials in Indonesia such as composite–metal joint technology, fiber and matrix production technology, and numerical analysis competency for modeling the composite.
