Maverick Rollbacks?

I was at Cedar Point during the big blackout.

^Cedar Point has gone through many blackouts before that even. It's nothing really new and like Maverick, every ride has its own system in place in case a power outage occurs.

Space Spiral usually has the most issues when it comes to power outages.

That's why Sandusky has the fire truck with the 300 ft. automated extension bucket/ladder. ;)

^LOL. The process of getting the cabin down is long and it gets quite hot in that cabin.

And you all thought it was hot in DT on the overheating lift hill. ;)

Okay, I'm done with the wisecracks now. Its late, I've been setting up for a huge concert at school for the past two days, and...I'll stop there. lol

As for Maverick rolling back, the LSMs will act as natural brakes, so to speak. A very complicated process (as was mentioned above), but in simplest terms, you don't have to worry about trains ramming each other should a rollback occur. *** Edited 5/19/2007 3:13:49 AM UTC by BlueStreak64***

We could always use the "Disney" way of explaining this stuff.

MAGIC :)

And its magic, if the music is groovy. Makes you feel happy like an old time movie...Sorry, couldn't resist that one. :) Wow, I think my mind is actually thinking in a joke-oriented way tonight.

You know...I was hoping I'd never see the earring thing again. I was happy after the Steel Phantom dropped the rule once re-configured.

Ill be honest. The rule somewhat concerns me. Does StormRunner have this rule? Especially since another notoriously rough OTSR coaster in the park *cough*Corkscrew*cough does not have this rule. It leads me to believe that Mavy could be more of a headbanger than Corkscrew...

Then again, maybe not... It just concerns me.

With the earing thing I think its a precaution becuase of the LSMs and the magnetic field as a precaution. Because of how powerful the LSMs are.

As for the Rollback Isssue, I learned electromagnets this year, and what I think it is is that Mavericks LSMs have a magnetic core and that core is enough to slow trains down their descent back to launch position. The reason for the electricity is to give the ride the "umph" it needs to make it up the hill and to navigate the course.

If anyone wants to correct me go ahead.

Are you serious about the LSMs and earrings? I hope not.

Someone else brought up the earring and LSM thing a while back. I found it quite amusing. Oh wait, never mind. They thought the "powerful LSM field" would damage their cell phone. LOL!!

Sorry im not an electrical engineer, however i was the one that stated that a while back about the cell phones. Some types of flash memory/hard drive based memory is effected by magnets. Just speculation at that point. I know that there is some threat of damage with some electrical components in large magnetic fields such as MRI machines. Just thought that a heavy rollercoaster train car would need just as much energy if not more than an MRI to power it up a hill...

I'm 14 I have a very creative mind when it comes to magnets.
:)

Nah, all the Maglev trains in the world have the same disclaimer in the stations about earrings.

;)

But can someone please tell me if my scientific conclusion three posts above was it true or not.

Are you talking about the magnets operating as brakes if the ride rolls back?

If that's what you're eluding to, have you read the first page of this thread?

Most of the magnetic fields used is contained within the LIM/LSM or magnetic brake. Magnetic field work best if formed in tighter loops, especially with an iron core. Any stray magnetic field is heavily shieded by the car's steel.

I have some N40 neodymium iron boron magnets. They have an internal magnetic flux of 1.29 tesla. This is about the same as the magnets used in the brakes and simular to the fields used on the LIM/LSM. With no shielding, they start to effect LCD and CRT about 6 feet away. With a 1/4 piece of steel placed on the end of the magnet, I can get it inches from the screen without noticeable effect. The car's shielding is heavier than that and there is much less stray magnetic field with LSM/LIM/magnetic brakes.

It would take a fairly sensitive magnetic flux sensor to even notice the magnetic field while on a roller coaster train.

Also, the reason for electricity is to add energy to the train. Energy is not created nor destroyed, just converted from one form to another. Brakes get away with this because the magnetic field is static and energy is not used from them, but the motion of the train ultimately feeds energy to produce the currents in the conduction plates (brake fins) via magnetic flux. The resistance in the plates form heat. The heat is where the kinetic energy is converted to.

In LSM or LIM case, they use electrical energy to add kientic energy to the train via magnetic flux. The more stray magnetic field produced, the less efficient the process. It is therefore not desirable to produce more stray magnetic flux than necessary.

Wow impressive :-) , What about water/rain? When the track will get wet from rain will the track completely have to dry before turning on the electricity again? Will the rain ground out the attempts of the electrical energy transfers that you were talking about?

The motors themselves are encased in an epoxy and are watertight. The power and signal lines for the motors and other electrical components are water tight and run through durable conduits to the electrical room. The electrical room stores the most sensitve components which is air conditioned and kept dry. Water simply isn't given the chance to cause problems.
