Diamondback Construction Thread (Updated 3-19-09)

I usually don't post here, but I found this an interesting subject of debate, so I figured I'd throw in my 10 cents. I'm a junior at Purdue in Mechanical Engineering(and also minoring in management and tech theatre, yeah I'm busy, and that's why I don't post in places often lol) which I applied to so that I could one day hope to have a shot at working in the industry.

My point being, is that this is something we are constantly told, to avoid what's known as "over the wall" engineering, which basically results in each phase of the project being very seperated from the other, many times because designers feel their design was "flawless" and any errors in the final product must not have come from the design, but rather manufacturing or installation. Aaron brings up a very good point, engineering is an interesting science in that you create rather than discover, and as such your rule book is literally the known physical laws of the world, which of course if fun because roller coaster's often turn your concept of physics on its head! But this rule book is very strict, and as designers B&M certainly knows, and has proven that they know, what specific tolerances must be taken on their end to ensure a smooth and reliable final product. But one can never fully underestimate that their design may have shortcomings, and I would imagine they will also be paying close attention to the test results, if for nothing else than to monitor if they need to adjust the trims/MCBR speed beyond what was originally expected. If B&M just took the stance, "we're B&M, we're friggin perfect!" to anyone who tested a ride designed by their firm and encountered problems, they likely wouldn't have the track record they currently hold.

Lesson of this, no design, no project, no building, no roller coaster, regardless how perfect the engineering, the drawings, the manufacturing, the installation, no part of the process is truly finished until the first train rolls out of the station with passengers. And even then, B&M knows they're just a phone call away from heading back to the drawing board on something if need be. If there's one thing I've learned from internships(priceless by the way for those of you in school/or intending on attending university), no design's perfect, no manufacture without its flaws, no installation without its mistakes. Not saying there's always something screwed up, but more often than not, expect something along the line will be, possibly even the design. ;)

It's nice to see another fellow Purdue ME on the boards to bring in some more knowledge. :) I'm a senior in ME right now.

As you mentioned it's true no ride is perfect, and if every ride is perfect there would be no need for trims. I've been harping on about the whole trim topic way back in this thread. The point of testing the ride and placing trims throughout is so B&M can ensure the ride stays within their design parameters. While I don't think we will see too much the the trims being used in the spring once Diamondback opens, I am sure we will see them starting to grab once the weather warms up and Diamondback is thoroughly broken in.

As for the whole Maverick debate, they didn't remove the element because the Gs were too intense, they removed it because after the first few rides, they felt that the heartline element was too 'uncomfortable' for the general public. What the hell that means, I don't know. No matter how well your design might meet G force criteria, it's always a fine line you are balancing between making a ride comfortable and thrilling, and a ride that may "that hurt like hell" and and be thrilling. Obviously, Maverick just crossed that line. IMO, Son of Beast literally took that line of rider comfort, crapped on it, made out with its mother, then gave it the finger.

Test runs on Diamondback are scheduled for Saturday and Sunday from approximately 2:00pm to 5:30pm at Kings Island, weather permitting.

If you are planning to head out to the park this weekend to catch a glimpse of Kings Island's new $22 million steel coaster please park and watch from Passenger Pickup located by the marquee on Kings Island Drive.

Hmmmm....

No pull through, I wonder who said they wouldn't but everyone said they would do it because they did it with Maverick.

**Ducking from flying objects

Don H. himself said that there would be no pull through. Since he is in a sense, the park, that is the only person I listen to. Keep in mind that while Diamondback is a B&M, Maverick is an Intamin AG coaster. I'm told that matters.

Okay, fine. Assuming this to be the case, would you or anyone else like to give a logical explanation for why the missing element from Maverick was removed after testing?

I was going to mention Maverick as well. I thought I'd heard that they had to take an element out after they tested and it was too harsh on the meters. I hope DB tests fine the way it is and they don't have to trim it up for an enjoyable ride.

The reason why heartline roll element was taken out is that it was giving to much stress on train and one guy rode it and show it up with bloody ear.

Grr I was so excited so I got ready real quick and headed out there. I got there at about 2:15ish and stayed until 3:00 and there was no sign of testing. I had my video camera ready and all but it never tested while I was there. Oh well.

It says weather permitting, maybe it's too windy?

This picture shows a nice view of the train and you can see the scoops in the very back. They are the tiny black things in the back I believe. The one question I have though is why every seat had a water dummy except one?

My guess that they want different weight on every seat so that why one seat not need water dummy.

^Do you ever proof read your posts before you post?? Just asking. Anyway.

Wind could be the issue, but I think the temperature has more to do with it today than anything. Sorry you didn't get to see any test runs today. I was up there today but I was just up there to process.

Yeah, like tycoonrebal said, do ever proof read your posts? Because in almost everyone of your posts you have mispelled common words and your grammer makes no sense at all.

We all had to learn and now its your turn :)

KICentral.com, an independent fan Web site devoted to Kings Island.The site, run by Ryan Suhr of Edgewood and Dane Thomas of Vandalia, Ohio, bid $600 with money from Web advertisements.

"People keep thanking us, but it was from people who so loyally visit the park," Suhr said. "It was our whole community that's responsible for that."

People -

If you exchange emails with the park please do not post them on the forums. Let's show a little respect. Emails are between two people, not between one person and the entire world. Posts containing emails from the park will be deleted.

Thanks,

Ryan

Don't tell that to people from Springboro. They might actually believe it. :lol:

Honestly, some of these people actually think the reason SOB's loop was removed is because the train fell during the loop. Also, my Health teacher was telling the class how 10 people died on Black Sunday (it came up because of something in our first aid lesson, checking the scene for safety before checking the victim).

I'm guessing that they will use that seat for a test dummy with sensors that detect the effects DB will have on its riders.

I'm guessing that they will use that seat for a test tummy with sensors that detect the effects DB will have on its riders.

Is a test tummy used to see if riders will get sick?

Tee hee...

Terpy, who liked that one...
