Over the past few days of working on research for this project, I have learnt a lot about magnetic levitation trains.
Magnetic Levitation Trains are 'floating' vehicles for land transportation that is supported by electromagnetic attraction and repulsion.
I discovered that maglev trains were first conceptualised in the 1900s by an American professor and a French engineer, Robert Goddard and Emile Bachelet.
I also found out that maglev trains utilise materials below for levitation and propulsion:
- superconducting materials
- electromagnets (hence the name)
- rare-earth magnets
I was introduced to two types of maglev trains;
- electromagnetic suspension (EMS)
- electrodynamic suspension (EDS)
and the differences between these two types;
where EMS uses attractive forces between magnets on the train and and magnets on the guide way, and on the other hand, EDS uses repelling forces between magnets on the train and magnets on the guideway.
I have learnt the benefits of maglev trains, which are:
- longer lifespan
(fewer materials need to be replaced due to the absence of rolling friction)
(maglev trains eliminates rolling friction, thus can reach higher speeds than conventional trains)
(the chances of derailment are lower than conventional trains)
- interior space options, comfortability
(design of maglev trains can be built wider than conventional trains, which means there are more options for how to utilise the interior space.)
- reduces air pollution
(no fuel is burnt, results in little to no air pollution)
- reduces noise pollution
(produces less noise than conventional trains due to the absence of rolling friction)
- less damage to landscapes
(do not need to excavate tunnels or manipulate landscapes to accomodate train tracks because maglev trains can work operate on higher ascending grades of up to 10 percent)
I have also learnt the disadvantages, which are:
- expensive cost of construction
(rare-earth elements are expensive to recover and refine)
I have completed most of my research and I am ready to move onto the second step of making the infographic.
One of the main things that have been challenging for me was time management. I have been struggling to meet the deadlines that I have set for myself, because I underestimated the amount of research I had to do. So I had to change my timeline a bit, so that I had more time to do the research, only to a point where I still had time to thoroughly edit.
This is my timeline and I have highlighted the things I have completed.
I have tried to set my timeline in a way where there is equal work distributed over each day, so that I am not cramming everything in one day. I have also scheduled my timeline so that I have almost everything done by 17th of March, which gives me time to ask my peers to give me some feedback.
Overall, I think my project has been going well, except for the fact that I had to reschedule my timeline, but other than that, I have been able to learn a lot about maglev trains and how they work.
