Re: Racing Simulators

JP:

This is interesting. I have not seen this one but did try a DP-100 in Las Vegas this past Spring that was set up very similar to this one. The pricing on that one was about $15K or so I beleive.

The one i used was so realisitic that when I really pushed the car toward the end of my session on a new track, I actually ducked instinctively as I rolled the car!

If you are seriously looking at these you might also ask Peter Artgesinger about a unit/group he was consulting with up near the Glen this year. I am not sure how far off from release they are but perhaps you could get an advance look.

Re: Racing Simulators

Do you have a release from the parents of those children to post their images on an internationally renowned web site?

Found pics on this internationally renowned website, but to be safe I have modified the original pics and added these other versions

Re: Racing Simulators

Your sims are out of my league!
I mispoke earlier on the simulator I tested in Las Vegas last Spring. It was the D-box gp-100.

Re: Racing Simulators

Sims sure have come a long way since I was a kid...

...although it does explain my current struggle for pace-- just didn't have the right technology in those crucial formative years

Re: Racing Simulators

These guys aren't using potato sleds, no siree Bob. Found this fascinating:
Simulation - computer technology and experience
BMW Sauber preparing for the Fuji circuit
21/09/07 12:46

Press Release
BMW Sauber

On the weekend of 30th September the Formula One circus will stop off at Fuji in Japan - a race track where none of the current crop of F1 cars has so much as completed a lap.

And yet by the Friday morning before the Japanese Grand Prix the set-up of the BMW Sauber F1 Team cars will already be very close to optimum. Advanced simulation programmes and the expansion of the team’s computer capacity on the back of support from Intel have been key to making this possible. However, experience has also played a critical role.

In late 2006 the simulation experts at the BMW Sauber F1 Team received the data on the new Fuji circuit as a CAD (Computer Aided Design) file from the race organisers in Japan. On the basis of this data, one of the team’s experts started by using a computer programme to establish the probable ideal line around the track. This process saw the circuit divided up into 500 to 800 segments through two stages. The radii for each individual segment were determined, allowing the experts to numerically define the ideal line.

The image of the circuit was then expanded to take on a further dimension, the engineers feeding the gradient profile of the race track into their computers. Inclines and downhill sections have a significant effect on the cars’ speed – especially on long straights. "In order to avoid losing precious time during the race weekend, we need to have as accurate as possible a picture of downforce levels, gearbox ratios and brake specification in advance," says Willy Rampf, Technical Director of the BMW Sauber F1 Team.

The engineers' next move is to define the car’s mechanical set-up. First, they use values taken from comparable circuits to establish weight distribution. Then the spring and damper settings are finalised, once again on the basis of empirical values. As Rampf explains: "It is, of course, an advantage that the Fuji race is scheduled so late in the year. We have collected a wealth of data with the F1.07 over the course of the season that we can use here in Japan."

The next piece of technology thrown into the ring is the lap simulation software. This highly specialised computer programme has been developed by the BMW Sauber F1 Team engineers and allows the crew to simulate lap times. Here the team starts by testing the car - in virtual form, of course - with various levels of downforce. The car is set up with a certain configuration, and the programme calculates the lap time that this will deliver. In this way, the engineers can determine the optimum downforce for the new circuit. A medium level of downforce has turned out to be the best compromise for Fuji. Another wave of numerous detailed wing settings will then be compared with one another shortly before the race in pursuit of further optimisation.

Now the focus shifts to working out the ideal gear spacing for the GP weekend. The top speed projected for Fuji - between 320 and 330 km/h on the long straights - prompts the engineers to set seventh gear first. This is followed by first gear. Here, an important consideration is whether first will only be used when pulling away from the start line or later in the lap as well. The remaining five gears are calculated on the basis of the engine’s output curve.

The lap simulation software is able to deduce the wear on the brakes from the levels of downforce on the car and the characteristics of the track. In simple terms, the key is to discover if the brakes are subjected to high, medium or low loads. The experts use these results to select the materials for the brake discs and pads and to finalise the specification of the brake callipers. Simulation technology also helps the engineers to establish the amount of cooling air required by the brakes. Brake ventilation plays an important role in aerodynamic efficiency: the smaller the vents, the greater the downforce generated by the car.

Even the most sophisticated computer processes cannot provide an answer to two major unknowns: one is the grip offered by the asphalt of the track surface, the other the level of tyre wear. Over to Rampf: "It is only during practice after completing some long runs - i.e. ten laps or so at a time with both tyre compounds - that we see how the tyres actually behave out on the track." This information provides the basis for the first strategy meeting of the race weekend, which takes place after the first two free practice sessions. Here, all the data collected so far is analysed and optimisation measures implemented.

This data is also inputted into the strategy simulation programme, which uses the full breadth of information available to calculate all possible race strategies. It then shows the engineers - to the second - how fast a one, two or three-stop strategy would be. Adding to the team's deliberations are factors such as the weather forecast and track characteristics, which will dictate how difficult it is to overtake. These conclusions are then examined and any new information brought to the table in the subsequent strategy meetings which take place on the Saturday and before the race on the Sunday.

"Our aim is to ensure that the lap times and top speed calculated using the simulation software do not vary by more than one percent from the actual values," says Rampf, indicating just how precise these calculations can be.

Re: Racing Simulators

Woof... Impressive.

Wonder if the F1 tracks get scanned with the kind of laser precision process that iRacing sims get. You would think so.

Re: Racing Simulators

Ford did this in the '60's in developing the GT-40 series cars to beat Ferrari at Le Mans. With 1960's tech, they set up a simulator where all the cars functions were worked on a dyno/test bed to "race" the Le Mans circuit for 24 hours at a time. Braking, throttle, shifting, clutch, steering, suspension were put through their paces to see what would break. Remarkable for it's day.

Ahhh...the GT-40 my favorite race car, in fact my new helmet will incorporate the gulf orange, blue, black color scheme. I spent many days reading about the GT-40's racing exploits during 4 months in the hospital recovering from my little party over in Vietnam. The one good thing to come out of that was it sparked my love for racing, there always is a silver lining.

Re: Racing Simulators

Never heard that before... As you say, very advanced for the time. In hearing stories of how much money was spent to develop and win with the GT-40 the amounts seemed extraordinary... but given what you are presenting here it makes more sense.

I am reading new book "racing in the rain" by John Horsman, the title is somewhat misleading. The book is about his years with top racing teams in that wonderful era of the GT-40, Mirages and Porsche 917's, all of which he was a part of. These were the golden years of sports car racing for me.

Re: Racing Simulators

In complete agreement with you Don. Those cars were and still are amazing given their performance envelop and the total absence of sophisticated computers, aerodynamics and tire technology to aid them. An amazing time.

The previous link would change the thread title to Racing Stimulators

I was looking for some nice GT-40 pics (really, I swear ) so opened supercars.net. An excellent source of hi-res car pics. Here is the Ferrari 330 page, surf from there.....

I just watched a dvr recording of the big Monterey weekend at pebble beach and the track. This has got to be one of those things to check off before the dirt nap. I may have to plan a road trip from Jackson next year, cars and wine for a week, i don't drink but i know plenty of ladies that do, cars will keep me buzzed.

Re: Racing Simulators

Problem with these types of simulators is its very unrealistic in one major way...the seat moves independantly from the steering. They really need to make it one big frame that moves, so you are not moving around the steering. CXC is another company that has a nicer version of this style simulator...but if you are mechanicaly inclined, you canbuild it yourself for couple grand.
