3. INTRODUCTION TO MAGLEV
• Imagine a train without wheels, how would it be different from the present
ones. They are maglev trains (come from magnetic levitation ).This
technology uses magnetic levitation to move vehicles without touching
ground( around 10 mm).
• Magnetic levitation trains have a great deal of uses and focal points like they
are faster by increasing the speed of 300 mph . It has no fuel utilization , cost
is less expensive than flights , quicker , environmental friendly , less upkeep ,
utilized in transport both traveler and goods , no non-renewable energy
source utilized , less commotion than conventional trains , takes less space
than traditional trains. They run by linear engines so they don’t need any
sort of large engines. Since they are not influenced by ground friction ; they
move much quicker than typical trains rather they would just have air
resistance or drag resistance.
4. EVOLUTION
• Growth of conventional one started in 1800s, ran at
110mph and at end of development of these trains .
Developed countries like France, Germany, Japan
develop bullet trains which ran at 150-180mph and
are costly, upkeep time consuming . Problem of
friction limits innovation and introduction to maglev
came into view.
5. HISTORY
• In 1902, first magnetic train is created by Alfred Zehden of
Germany. Recieved two patents in 1902 and 1907.
• In 1979, first magnetic train was worked in Hamburg, Germany.
• In 1984, the first train the individuals could ride was worked in
Birmingham, England.
• In 2004, the high speed Maglev that individuals can ride on was
made in Shanghai, China.
• Maglev transport frameworks are presently operational in only
three nations (Japan, South Korea and China). That are Shanghai
maglev(2004), Linimo (Tobu Kyuryo Line ,2005) ,Daejeon Expo
Maglev(2008), Incheon Airport Maglev (2016), Changsha Maglev
(2016) and Beijing S1 Line (2017).
6. WORKING OF
MAGLEV
• The train skims over the
guided way by changing
magnetic fields. The full
guideway is putted with
electromagnets which
helps from side
movement.
• For it to be above 1 cm a
computer required to
measure the current.
• Three basic things for a
maglev to work:
Levitaion, Propulsion and
Guidance.
7. • LEVITATION -
Levitation is the
capacity for the train
to remain suspended
over the track. Two
types levitation
technology: EMS and
EDS.
8. • PROPULSION-Propulsion is the
power that drives the train forward.
• GUIDANCE- Its the way on which
the train moves and it is kept in centre
due to repulsion between the levitaton
and guideway magnets.
9. CONCEPT OF ENERGY USE
• Energy in maglev trains is utilized to increase the speed of the train.
• A large portion of the energy is required in overcoming the "air drag".
Some energy is utilized for cooling, warming, lighting and other things.
• The energy per unit time used in overcoming air drag increments with
the cube of the velocity and henceforth dominates at high speeds. The
energy required per mile increments by the square of the speed and the
time decreases linearly.
10. LIMITATIONS AND ADVANTAGES
Advantages –Because of no
friction there are number of benefits:
1. No wear and tear , so upkeep cost
decreases by huge degree.
2. No resistance ( no contact). Also
electromagnetic drag and air
friction does not interfere in
achieving speed more than 200
mph.
3. No noise, environment friendly,
weather proof and more secure.
Disadvantages – Reasons
hindering development of maglev
are: Large beginning investment and
not enough for replacing the already
running ones.
11. INITIATIVES
• Numerous maglev frameworks have been proposed in different
countries of North America, Asia, and Europe. Huge numbers of
the frameworks are still in the early arranging stages. However, a
couple of the accompanying models have advanced past that
point.
• United Kingdom ( London)– Glasgow, Japan( Tokyo - Nagoya -
Osaka), China (Shanghai) – Hangzhou, La Guaira in
Venezuela(Caracas), Nevada Interstate Maglev and Washington
D.C.Maglev in California and Baltimore of United States
respectively etc.
• India is also taking initiatives for installment of maglev.
• Mumbai – Delhi, Pune (Pimple Saudagar) – Mumbai (Panvel) ,
Chennai - Bangalore – Mysore, Mumbai – Nagpur.
12. FEASIBILITY AND
RELIABILITY
For achieving high speed steel rails with no
bends need to be installed which are again
high investment. Maglev train requires steel
rails, establishment cost of these rails is high
yet the upkeep cost is low. When the rails are
introduced we don't have to pay any cost for
its assessment or maintenance.
The higher energy brings about greater
expense and then the cost of these trains will
be more than the air toll and these trains will
be past the reach of regular man.
The working expense and making of bridge
extensions makes it exceptionally high.
13. COMPARISION
Conventional Trains- No contact( no rolling
friction), more energy utilisation, less
commotion , no wear and tear, 300 mph
faster than conventional ones.
Aircrafts- Insted of more air drag runs more
productively, due to climate flifgts postponed(
similar speed in all seasons), maglev prices
not affected by oil markets, no landing
mishaps, no obstacles(not as high speed as
aircrafts). In air travel, time is likewise being
wasted (essentially in occupied airports ) by
the airplane for taxing, hanging tight in line for
take-off and landing, which are trivial if there
should be an occurrence of maglev
14. FUTURE
• It can possibly be a quicker, more secure, and ecological type
of transportation than we have today. There are potential
applications for this innovation in anything from intercity
open transportation to cross country trips. There are even
recommendations to manufacture long underground vaccum
tubes. While it might be quite a while before this innovation
gets common, it is hard to deny that it will sooner or later be
pervasive. By what method will this innovation advance and
improve as we move into future? The truth will surface
eventually. However, it is profoundly conceivable that we
presently remain at the cliff of a transportation revolution.
15. Why we are still lacking in their
development?
The Maglev train is considered for both urban
transportation and intercity transportation frameworks.
Researchers are certain that this innovation can be
used for train application as well as airplane and rocket
launching frameworks. The requirement for another and
better transportation framework has urged numerous
nations to be keen on an endeavor to build up the
Maglev train. However, even though after having many
advantages , why maglev’s are still not expanding?
Notably since it's new and generally untried innovation .
This what makes it still untried as it costs much than the
installation of conventional trains. But instead of having
this disadvantage it is still better because once investing
money in it , it don’t need any further upkeep cost , no
fuel and many other benefits are there . It will be great
in looking forward to floating across the countryside at
300 mph in a levitating box of magnets.
