Design And Analysis Of A Regenerative Braking System For City Bus (Anbesa Bus)

Abstract

Now a day environmental pollution is getting worse day to day and energy crisis that would implicate to the global economy. In a car the energy is waste, environmental pollution and fuel consumption is occurred during braking. Brake is a mechanical device used to slow or stop the vehicle with the smallest distance by converting the kinetic energy of the vehicle into the heat energy which is dissipated into the atmosphere. So, just in case of car one among these useful technologies is that the regenerative braking system. Regenerative braking system is an energy recovery mechanism converting its kinetic energy into electrical energy during braking which can be either used immediately or stored until needed. This thesis aims to design and analysis of the regenerative braking system for a city bus (Anbesa bus) by direct gear engagement of regenerative braking system to the engine flywheel using pinion gear. The overall design of the regenerative braking system involves material selection for the components and the design of subsystems. The subsystems of the regenerative braking systems are Mechanical subsystem as a power transmission throughout the system while being physically connected one another, Pneumatic subsystem use compressed air from air brake reservoirs during braking to actuate the clutch by using fork lever, and Electrical subsystem responsible for converting the transmitted rotational mechanical energy into electrical energy and store the generated energy for usage at the instance of need. The generated electrical energy by the regenerative braking system is used on the bus to provide an extra electric power source used to run specific bus electrical accessories to enhances the attractiveness of the bus. In the process of the design relevant assumptions were taken, the component specifications and dimensions are determined, component failures were checked by using mathematically and Ansys software. mechanical simulation is done by using solid work 2017 software, simulation of pneumatic and electrical system is done by using pneumatic Festo and mutism software. Finally, the total kinetic energy recovered by the system at 2300 rpm is 26095.6 KJ and the efficiency of the system is 84%.
