3. INTRODUCTION
• Now a day’s , vehicle energy harvesting and improvement of
energy efficiency has become more popular.
• Only 10-16% fule energy in the vehicles is utilized for driving to
over come resistance from road friction and air drag ,one most
important loss is kinetic energy dissipated by shock abosrber.
• The function of vehicle suspension system is to support the
weigth of vehicle body.

4. • Suspension is a important source of energy dissipation.
• We aim to develop a product design to harvest the energy from
motion an thermal losses in vehicle engines to better meet
tomorrows power demands in the automotive industry.

5. LITERATURE SURVEY
PAPERS AUTHOR JOURNALS SUMMARY
A preliminary study
of energy recovery in
vehicles by using
regenerative
magnetic shock
absorbers.
Goldner rb,Zerigian
and Hull.
SAE paper This paper proposed
electromagnetic(EM)
shock absorbers to
transform the energy
dissipated in shock
absoebers into
electrical power.
Design of
electromagnetic
shock absorbers.

Mulcahy and hull jr
Mechanics and
material design
Thay mention that
energy regeneration
is small and may be
relevant only for
electric vehicles.
Structure and
performance analysis
of regenerative
electromagnetic
shock absorber.
Zhen longxin and Wei

Networks The innovative shock
absorber resembles
linear generator in
principle and can
generate electric
power through the
relative motion b/w

6. OBJECTIVES
• The design of the system that will converts kinetic energy into
electricity instead of heat through a Linear Motion
Electromagnetic System.
• Electricity is then converted into direct current through a full
wave rectifier and stored in the vehicle‟s betteries to increase
battery life.
• Possible to implement in vehicle suspension with minimum
design changes.
• Can harvest energy in both expansion and compression.

7. REQUIRED MATERIAL FOR CONSTRUCTION.
• ELECTRICAL COMPONENTS
Battery
Electromagnet
Rectifire and capaciter
• MECHANICAL COMPONENTS
Frame structure
Cylinder and piston
Permanent magnet
Coil spring

8. VIEW OF COMPONENTS.
• Battery
• Rectifier
• Capaciter

9. • Cylinder and piston
• Permanent magnet
• Coil spring

10. • Suspension systems which is a main part of assembly.
• Stator windings and permanent magnet are the main parts of
the construction.
• Bridge rectifier-It is an arrangement of 4 diodes in a bridge
citcuit. Configuration that provides the same polority of output
for either polority of input.
• Capactior-It is apassive two terminal electrical component used
to store energy in the form of electric charge .

12. WORKING
• This works on the principle of faraday’s law of electromagnetic induction.
• Explains that when ever the magnetic flux linked with a circuit changes, an
EMF is always induced in it.
• When shock absorber come into action simultaneously stator winding comes
into action.
• The flux cuts the permanent magnetic field ,due to this EMF is induced.
• Due to the EMF effect, the current is produced.

13. • The bridge rectifier converts the alternating current to the direct current.
• The current can be used for lightening of bulbs or it can also be stored in a
capacitor.

14. MERITS
• Shock absorbers have a great for performance, handling and stability. They
are best choice for work and severe use vehicle
• It improves fuel economy and cost saving.
• Continous supply of energy.
• Simple in design
• Energy efficient performance and long lasting reliability

15. APPLICATIONS
• In military areas
• Commercial trucking industry
• This technology can be applied to any type of vehicle
• In industrial access
