OVERVIEWIn today’s 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 .

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 OperationThe 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 SPECIFICATIONRack: 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 = 22cmNo of turns = 20Wire Dia = 1 mmMaterial = copper Alloy

• Bearing: Inner Diameter(d) = 20 mmOuter Diameter(D) = 30 mm ISI NO = 10BC02Bearing no = 6200Material = steel

Shaft:Dia of shaft = 16 mmLength = 200mmMaterial = High grade steel

• Sprocket Wheel:Sprocket Dia = 50 mmMaterial = Cast iron grad A

Chain Drive:Length = 700 mmChain Width = 7 mmMaterial = 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 mmOuter dia of spring(D) = 4 mmNo of coil (n) = 20Mean coil dia = D-d = 3 mmStiffness of spring k = G×d^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 = 80mmWeight acting on speed breaker = 15.3* 9.81 = 150.09 NWork done = force * displacement

= 150.09 * 80/1000 = 12JPower obtained for one pulsing = 12/60 = 0.2 WattPower 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 ohm’s law, P = V*I

= 1.88*17*10^(-3) = 0.03Watt.

Efficiency:η = (Theoretical Power - experimental power)/

Theoretical power

= (0.2-0.03)/0.2 = 0.85

%η = 0.85*100 = 85%

Result:Load (In KG) Voltage (in volt)

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.

AdvantagesPower 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.

DisadvantagesOnly applicable for the particular place.Mechanical moving parts is highInitial cost of this arrangement is high.Care should be taken for batteries

ConclusionsGovernment 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.
