4. Introduction
► In the present scenario power becomes major need for human life.
► Due to day-to-day increase in population and lessen of the conventional
sources, it becomes necessary that we must depend on non-conventional
sources for power generation.
► The quest of abundance power we decide to gather waste of kinetic
energy from vast growing automobile industry.
► While moving, the every vehicles posses some kinetic energy that can be
gather into electric form by mechanical conversion but it is being wasted till
now.
► Concept power generation from speed breakers which are
found in every road corner and collection of small power few
Watts into mega Watts.
Energy cannot be Created or Destroyed but it can be Converted from one form to another.

5. Fulfilment of Energy
~Around Urban 2.7cr (27 million) Street lights light up the nights in Urban India.
Which is Increasing day-by-day by Govt. of India.
~Average Street light Consume 30W of power and total 81 LAKHS KWh FOR
~2.7cr lights daily. This can light Up 6 lakhs Houses daily in Night.
~There are 38 lacks (3.8million) Vehicles on road in India. stat by Govt.of India
and the Running Vehicles are LOSING POTENTIAL TRANSFERABLE ENERGY.
► This kinetic energy can be utilized to produce power by
using a special arrangement called POWER HUMP.
► The Kinetic energy of moving vehicles can be converted into
mechanical energy of the shaft through rack and pinion
mechanism.
► So, the power can be generated.
! IT WON’T TAKE MUCH ENERGY, TO CONSERVE ENERGY

6. WHAT IS SPEED BREAKERS
► On June 7, 1906, precisely in Chatham, came out the first speed bump in the
history made of flagstones and cobblestones. Crosswalks where raised by few
centimeters above the road level to lower the speed of cars that bothered the
1,400 resident of this village.
► Speed Breakers is used for decreasing speed of any vehicles.
► Speed Breakers put in to the mid of the road, where there more traffic are
possible, or in crowded area. To reduce the possibility of accident by reducing
speed of vehicles.
► In 1973, the British Transport and Road Research Laboratory published a report
about different types of speed bumps (CIRCULAR,PARABOLIC,FLATS)
During that time, speed bumps where places only in private areas.

7. SPEED BREAKER’S
ADVANTAGES
➢ The purpose of installing speed bumps
was to reduce speed not only in the
private areas but also in public streets.
When the driver see the speed bump, he
is obliged to reduce his vehicle speed.
Thus, safety of pedestrians and drivers is
taken into consideration. Figure shows
the different shapes of speed bumps.
The most common shapes are circular
and parabolic, flats.
DISADVANTAGES
➢ vehicles get damage if passed over fast.it
cause high impact on vehicle dynamics.it
cause discomfort to people riding to it may
cause chronic backache.Besides Emergency
running vehicles will get delayed due to
acceleration and deceleration. it can cause
vehicle noise.Besides, large vehicles can lose
control if they pass over bumps at high
speed.Moreover it can increase Fuel
Consumption

8. BASIC PRINCIPLES
► Simply, Weight (potential energy) and kinetic energy converts
into mechanical energy.
► And again mechanical energy converts into electrical energy.
► It is Possible using 3 different mechanism:
1. Crank-shaft mechanism.
2. Roller mechanism.
3. Rack-pinion mechanism

9. HOW IT CAN BE USED FOR POWER GENERATION?
► Generally, the vehicles are moving from-on speed breakers.
► When the vehicle pass through the speed breaker, if there
mechanical mechanism put inside the speed breaker, the breaker
will press down due to the weight and kinetic velocity of
vehicle.this pressing will make movement of gears arrangement.
► So, by the help of gear movement mechanism, Power can be
generated.
► And the speed breakers can used for power generation.

10. USING Crank MECHANISM
► Crankshaft are required to be mounted on bearings which
creates balancing problem leading to mechanical vibrations
which in turn damage the bearings.
► Secondly as bearing are of sliding type, any occurrence of
variable load (which is bit obvious in case of vehicles) leads
to balancing problem.

11. Crank MECHANISM Type
► The crankshaft transforms circular motion to a reciprocation
motion or vise-versa. A crank is an arm linked to a shaft with a
precise angle. When the vehicle passes over the speed
bump, the vertical motion is changed to a circular motion.
Afterwards, the dynamo, linked to a spur gear attached to a
shaft rotates and produces energy. Figure 6, shows the main
steps of crankshaft design to transform the mechanical
energy into electricity

13. ROLLER MECHANISM
Advantages
► Construction is Simple
► Less Operational Parts
Disadvantages
► Roller mechanism has some different
disadvantages.
► Maintenance will be very difficult.
► Might cause collision.
When the vehicle passes over the
speed bump, rollers rotate and
allow the dynamo linked to a
rotor shaft to rotate and produce
electricity

21. WORKING Of Rack and Pinion
► This project explains the mechanism of electricity generation from speed breakers.
► The vehicle load acted upon the speed breaker system is transmitted to rack and
pinion arrangements.
► Then, reciprocating motion of the speed-breaker is converted into rotary motion using
the rack and pinion arrangement where the axis of the pinion is coupled with the
sprocket arrangement.
► The sprocket arrangement is made of two sprockets. One of the sprocket is larger in
dimension than the other sprocket.

22. ► Both the sprockets are connected with chain which
transmits the power from the larger sprocket to the
smaller sprocket.
► As the power is transmitted from the larger sprockets to
the smaller sprocket, the speed that is available at the
larger sprocket is relatively multiplied at the rotation of
the smaller sprocket.
► The axis of the smaller sprocket is coupled to a gear
arrangement.

23. ► Here we have two gears with different dimensions. The
gear wheel with the larger diameter is coupled to the
axis of the smaller sprocket.
► Hence, the speed that has been increased at the
smaller sprocket wheel is passed on to this gear wheel of
larger diameter.
► The smaller gear is coupled to the larger gear. Therefore,
as the larger gear rotates it increases the speed of the
smaller gear which is following the larger gear and
multiplies the speed to more intensity.

24. ► Though the speed due to the rotary motion achieved at
the larger sprocket wheel is less, as the power is
transmitted to gears, the final speed achieved is high.
► This speed is sufficient to rotate the rotor of a generator
and is fed into the rotor of a generator.
► The rotor which rotates within a static magnetic stator
cuts the magnetic flux surrounding it, thus producing the
electric motive force (EMF).

METHODOLOGY Of Rack and Pinion
Translation Stress The car apply a force F on the bump, which is defined as
a kinetic motion.
Mechanical Guidance and Rotational Motion The force in translational
motion changes in rotary motion because of the rack and pinion
Electrical Power The force is then transformed into an electrical power by
the generator
Storage and Lighting The electricity is then stored in batteries to be ready
to use for supplying necessary devices such as public lighting for streets or
even traffic lights

26. CALCULATIONS Of Rack and Pinion
With its elastic capacity, when a force is applied in this case vehicle-
a mechanical energy is stored due to compression and stretching.
The problem can be faced is that the spring can break down due
to larger deflection .
To know magnitude of force that is applied,
Spring Constant Formula is used:
K= spring constant
F= forced applied
X= extension of the object
F=Kx
Springs

27. CALCULATIONS Of Rack and Pinion
The Rack is linked directly to the bump. The vertical motion is
transmitted and cause the rack to move vertically downward. The rack
is also linked to a pinion that rotate in one direction only. Thus, the
vertical motion is turned into rotational motion.
To know the maximum torque that is by the entire system:
Θ= Angle made between the rack and pinion
F= force required to give the spring maximum depression
r= radius of the pinion
τ= r F sin θ
Rack and Pinion

28. Other Components Of Rack and Pinion
After, the vertical motion is turned into rotational motion, the pinion transmit the energy to the sprocket,
which constitute of two wheel with teeth that has meshes linked to the chain that causes torque. The
upper wheel is the one connected to the pinion and the other wheel is connected to the generator
Sprocket and Chain
Electrical Components
Generator
In this case, we will use a generator not a motor since the generator is a device that transforms the
mechanical energy into electrical power whereas, the motor transforms the electrical power into
mechanical force. The generator uses electromagnetic induction principle.
Rectifier
It is the device that transforms the AC power to a DC power and vice versa. It is mandatory in this
mechanism since it will transform the AC power produced from the generator to a DC power ready to
be stored in batteries.
Batteries
The device stores the DC power in order to transport it to street lighting. Since most of street lighting
nowadays uses LED lighting, it is important to have inverter in order to provide the street and traffic
lighting system with DC power

32. ADVANTAGES
► Maintenance and installation cost are low.
► Electricity Produced on daily basis.
► Simple Construction.
► Less floor area required.
► Pollution free power generation.
► No need of manpower during power generation.
► The project is easy to install.
► The project is eco-friendly.

33. OUR GOALS AND MOTIVES
► Don’t want to see India as an energy deficient country.
► It should be of least cost, as well as of less weight.
► Efficiency should be as high as possible.
► Losses should be minimum.

34. FUTURE SCOPE
► The shortage of light can be reduced at some extent.
► Wastage of energy can be minimized.
► Flywheel can be used to increase the rotational speed
of the Dynamo shaft.
► It may also be used for light vehicle.
The design is to be studied in future work for further details such as
friction forces and gravitational force. The idealogy conducted in
this project design is the ideal case where all external forces are
excluded. However, to have a more realistic result, a more
accurate study should be conducted. Moreover, the gear box will
also be taken into consideration in the future work. Besides, the
chain in the sprocket and chain assembly can be replaced by
the belt.

35. CONCLUSION
► It is an non conventional type of producing the energy.
► Existing source of energy may not be adequate to meet the
ever increasing demands, So this project is a one step to
path off that way.
► This project will be helpful to solve some of the Electricity
shortage problems.
From this project, we conclude that speed bumps
generating electrical power are very efficient when it
comes to producing electricity. The entire project assemble
both mechanical background and electrical knowledge to
come up with the idea of creating electricity from a source
that is not harmful for the environment. The theoretical study
shows that the design is very efficient since only a Couple of
100s kg mass that goes aver the bump can produce 90 W of
energy. In other words, it can supply enough electricity for a
one streetlight of 70W, which is a considerable amount of
energy even if we try avoid all the energy loses and try to
mass installation and prodcustion overall cost can be
reduced to minimum.
