This year, when Indy 500 teams search for a competitive edge, they're going to have to dig deeper into the mechanical aspects of the car than ever before in the history of the race.
"In years past, we had a bit of an open book in terms of the changes we could make, but they've really tightened up the rules in recent years," Mark Johnson, general manager of KV Racing Technology, told Design News. "We're tightly controlled in our friction and drag reduction. We even have 'spec' bearings that we have to run. So these days, it comes down to attention to detail."
Indeed, attention to detail will be the key for most teams when they hit the track on May 27. While there will be little leeway in the terms of engines, chassis, and bearings, race teams will have legal avenues to engineer their vehicles by tweaking the design of dampers (shocks), lubricants, and gearbox coatings.

Employing simulation techniques, teams are able to customize those parameters. "We spend huge amounts of time on seven-post shaker rigs that allow us to run a replay of any track," Johnson told us. Running data from any race course, the shaker rigs can simulate turns, G-loads, and even little undulations in the track, enabling engineering teams to optimize the settings on the vehicle's dampers and its springs to match the race track.
"If you have one of these machines in-house, you could be at the race track on a Friday afternoon, run a practice session, stream the data back to your race shop, download into it into your computers, and then run that course on the rig," Johnson said. "Then the race shop can email back the results to you at the track."
He said that race teams employ the results of their simulations in different ways. Some change the settings on supplier-based dampers, while others build their own custom dampers, based on the simulation results. "The 'internals' of the dampers are one of the biggest tuning tools available to us this year," he said.
Real racing is when the contest is between ideas and determination translated into speed. Racing isn't about rules, it's about exceeding the limits and enlarging the envelope.
I like the fact that the automakers are willing to pony up with big bucks to develop the sport. The gain for them is the bragging rights that they are technologically "in the game" and ahead of the other car makers, and that's worth it for them (or else they would cut off the money).
The trick for IndyCar is to finess the rules to harness that money and effort in a productive way to encourage real innovation (the way Indy used to be) and make it more than just a bunch of cars driving in a circle. Unfortunately, judging by this (how many angels can you fit on the tip of a needle [bearing] ?) IndyCar is not succeeding.
I understand why IndyCar had to step in and place controls on the technology side of this. When Toyota spends $1 billion in five or six years, then, yes, I suppose controls have become necessary. What I don't understand is why everyone kept upping the ante until that became necessary. At some point, I would think these automakers and race teams would have behaved the same as anyone in a high stakes poker game and simply said, "It's too rich for my blood."
For real racing innovation and fun one only needs to attend a local short track where backyard mechanics still thrive. Shoe string budgets, making do with what you have, and close competition is seen in the lower divisions. For the fan, you can actually see the cars go by and relate to most of the vehicles. The drivers love to talk with fans and actually have time to show people their cars.
I'm old enough to remember the fun days of Can AM racing where almost anything went – The innovation was exciting. We could hardly wait until the next race to see what guys like Jim Hall would bring to the track.
Over regulation just give us cookie cutter cars that are boring!
As I think about it, the even greater shame is the lost opportunity to inspire the next generation of engineers and scientists. Without a visible platform to demonstrate the technology, it really is just a bunch of cars going around in a circle.
That is how so many problems are caused - lack of balance. Where does striving to improve enter the realm of overreactive control? Not easily answered and often the folks behind an initiative have the best of intentions...this issue is common in so many endeavors and it is often not until the distance of history that the error is recognized.
I don't know if I should be appalled or depressed. Or both. Probably both.
This is a problem of the Indy controlling authority micro-managing the engineering in all the wrong ways. OK, I understood when they outlawed active control surfaces because people were dying when they failed. But this level of hamstringing (spelling?) Engineers is beyond absurd. Specifying which bearings can be used? Tuning lubricants to specific tracks? Let's vacuum all the fun out of racing, then vacuum it out some more.
Besides, human beings drive these vehicles, so any effect that a lubricant may have on the outcome of a race is lost in the noise of operator limitations, error, and habit.
Since the money that goes into this industry is obscene, let the Engineer's loose and see what they come up with (like it used to be). The whole benefit of having Indy (socially) is that it's bleeding edge technology that winds up (slowly) available to the rest of us (i.e. a technology incubator).
Want to make it really interesting? Spec out the driver completely. Then they will have to start Engineering better sensors and processors, improving reaction times, which will wind up (in a decade or so) in our street cars and save countless lives.
End of my rant (and don't even get me started on Nascar of the NFL).
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
With LEDs dropping in price virtually every year, automakers have begun employing them, not only on luxury vehicles, but on entry-level models, as well.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
