Experimental investigation of effortless hybrid human powered vehicle: New insights into bicycle

Abstract

This work is dedicated to possibility of human power vehicle in urban and rural transport systems. Due to the need to look for alternative solution for fossil fuel with conventional drive systems, Human powered vehicle is one of the practical possibilities for sustainable transport systems. It also improves independence from imports oil which is one of the main priorities of countries like India. The vehicle which driven by human power i.e. muscular energy will provide an immediate solution to mechanical challenges and fuel limitations. This Research will deals with developing mechanism of high speed effortless Human Powered Hybrid Vehicle. Hybrid HPV vehicles are powered by peddling and an electric motor, which uses energy stored in the batteries. The kinetic energy will be store in the battery and utilized at the time of needy condition. The main objective behind this research is to build alternative mode of transportation, which would utilize human energy in an efficient way and will also compute with conventional vehicle. The mechanism is used in the HPV which increases input energy like step up transformer and indirectly increases the speed of HPV. The mechanism is attached with a pair of Neodymium magnets (NdFeB) along with slider to transmit motion in forward direction only. Force in the Neodymium magnets is transferred and utilized on the rear wheel which helps to reduce the pedaling force applied by the rider. The motor generator used in HPV performs both the drive and regeneration functions. The developed HPV [Magnet used NdFeB N42 (50 X 15)] can achieve speed of 32 kmph with pedaling rate of 70 rpm, this will provide an alternate for fuel propelled vehicle.
