Bullet And Magnetic levitation Trains
Bullet Trains
History
- 140-250 mph
- aerodynamics
- shocks, spoilers
- pantographs
- Peter Cooper- (1830)steam engine
- Rapid expansion
- The slowdown for trains
- A Greener Earth and overcrouded
The main problem
Maglev Trains
Problems with bullet trains
- no friction!
- at least 300 mph-350
- minimum maintenance
- weather
- lower cost to run
- charges itself
- emf=-N(phi)/t (faradays law)
- Hunting oscillation (forces)
- regular maintenance
- weather
- all wheel drive
- arching---->
plasma arc discharge
EDS Vs EMS
How they work
demonsrtation
EDS VS EMS
- levitation--->
- ac current
- frequency
- push/pull
- position sensor
- superconducting
- suspension
- speed
- safety
- more maintenance
