Modelling and Design of an Auto Street Light Generation Speed Breaker Mechanism

Energy usage is inevitable to Man’s daily living. For any task to be achieved in life energy must be converted from one form to another. This method of power generation is one of the most recent forms of energy generation concepts. The mechanism converts the kinetic energy of vehicles at speed bump into electric energy. A preliminary modelling of the speed breaker system was developed. The component members were designed and modelled on SolidWorks software based on the properties of the selected materials. A static and fatigue analysis of the spring using SolidWorks reveals a yield stress of 172.3 Mpa. The computational fluid dynamics of the air reveals an average total pressure and velocity of 29.74 bar and 1.018 m/srespectively.The conceptual design was carried out and resulted to the selection of materials needed for each component of the design. A prototype of the speed breaker mechanism was constructed and tested. The mechanism generated 6V D.C which validates the principle. The light sensor automatically opens the valve to on the light when it is dark and closes it to off the light at dawn.
