The document describes a hardware project to design a speed breaker power generation model using a rack and pinion arrangement. It includes 6 team members and their guides. The project aims to convert the kinetic energy of passing vehicles into electrical energy. It works by using the rack and pinion mechanism to convert vehicle movement into rotational motion that turns a generator to produce electricity stored in a battery. The major components, design specifications, theoretical power calculations, experimental results and advantages are provided.

OVERVIEW In todays world, almost every equipment requires electricity for its working. This is one of the conventional method for the generation of electricity from the otherwise wasted energy. All moving vehicles possess kinetic energy, which can be used for the generation of electricity. When a vehicle passes through the speed breaker it generates electricity.
AIM To design and develop a speed breaker power generation model with rack & pinion arrangement.
Working Principal The kinetic energy of the moving vehicles can be converted into mechanical energy of the shaft through rack and pinion mechanism. This mechanical energy will be converted to electrical energy using generator which will be saved with the use of a battery . [A]
Rack Pinion Mechanism [B ]
Working Operation [C]
Working Operation Vehicle load acted upon the speed breaker system is transmitted to rack and pinion arrangements. Reciprocating motion of the speed-breaker is converted into rotary motion using the rack and pinion arrangement. The sprockets are connected with chain drive which transmits the power from the top sprocket to the bottom sprocket. The axis of the bottom sprocket is coupled to a spur gear arrangement. Speed is sufficient to rotate the rotor of a generator and is fed into the rotor of a generator.
Working Operation The rotor which rotates within a static magnetic stator cuts the magnetic flux surrounding it, thus producing the electric motive force (emf). This generated emf is then sent to an inverter, where the generated emf is regulated. Regulated emf is now sent to the storage battery where it is stored during the day time and can be used in night time .

DESIGN SPECIFICATION Rack: Length of Rack = 150mm Number of Teeth = 40 Material = Cast Iron Grade A Pinion: Dia of Pinion = 25mm Number of Teeth = 22 Material = Cast Iron Grade A Spur Gear: Dia of gear = 60mm Number of Teeth = 50 Material = Cast Iron Grade A
Closed Helical Spring: Spring length = 22cm No of turns = 20 Wire Dia = 1 mm Material = copper Alloy Bearing: Inner Diameter(d) = 20 mm Outer Diameter(D) = 30 mm ISI NO = 10BC02 Bearing no = 6200 Material = steel
Shaft: Dia of shaft = 16 mm Length = 200mm Material = High grade steel Sprocket Wheel: Sprocket Dia = 50 mm Material = Cast iron grad A Chain Drive: Length = 700 mm Chain Width = 7 mm Material = steel
Wooden base: Size = 310mm X 150mm Cast Iron Bar(H Frame): Size = 400mm X 220mm Speedbreaker: Height = 80mm
Power & Load Calculations: Material of spring = ASTM A240 steel(G=40GPa) Wire dia of spring (d) = 1 mm Outer dia of spring(D) = 4 mm No of coil (n) = 20 Mean coil dia = D-d = 3 mm Stiffness of spring k = Gd^4 /8 D3 n = 1.5 N/mm
Power & Load Calculation(Theoretical ): Stiffness of spring k = Load/Deflection of spring under load LOAD = K* Deflection = 1.5*50 = 75 N This load acting on one spring but we consider two spring ,so total force acting on both spring = 2*75 = 150N Mass acting on both springs = 150/9.8 = 15.3kg Now we consider mass of body acting on speed breaker is 15.3 kg
Height of speed breaker = 80mm Weight acting on speed breaker = 15.3* 9.81 = 150.09 N Work done = force * displacement = 150.09 * 80/1000 = 12J Power obtained for one pulsing = 12/60 = 0.2 Watt Power obtained in one day = 0.2*60*24 = 288 Watt = 0.288KW Power & Load Calculation(Theoretical ):
Experimental Calculation: The generated output voltage in one pushing forces of speed breaker . V = 1.88 v Current in the circuit in one pushing forces of speed breaker. I = 17 mA As per ohms law, P = V*I = 1.88*17*10^(-3) = 0.03Watt.
Efficiency: 侶 = (Theoretical Power - experimental power)/ Theoretical power = (0.2-0.03)/0.2 = 0.85 %侶 = 0.85*100 = 85%
Result: Load (In KG) Voltage (in volt) 5 0.68 10 1.12 15 1.97
Cost Analysis:
Future Scope [F] Eco-Friendly Energy Generation through Speed Breaker. Suitable at parking of multiplexes, malls, toll booths, signals, etc. The shortage of light can be reduced at some extent. Wastage of energy of vehicles passing on roads can be minimized. Such speed breakers can be designed for heavy vehicles, thus increasing input weight and ultimately increasing output of generator.
Advantages Power generation with low cost and using non- conventional energy sources which will help us to conserve the conventional energy sources to meet the future demand. By using this method, electricity will be generated throughout the year without depending on other factors. Easy for maintenance and no fuel transportation problem. Pollution free power generation. Less floor area required and no obstruction to traffic. No need of manpower during power generation.
Disadvantages Only applicable for the particular place. Mechanical moving parts is high Initial cost of this arrangement is high. Care should be taken for batteries
Conclusions Government focuses on utilizing the non-conventional energy sources for electricity generation and reducing the share of global warming. The techniques described in our project will also contribute to the power generation nationally with some more modifications in the model. As per our survey we conclude that Rack and Pinion mechanism is efficient [G] as well as cost effective mechanism for generation of electricity from speed breaker.
