Qualifying Preparations

Posted Fri, 10/23/2009 - 10:06am by Steven Hechtman

With our first pass through scrutineering yesterday, and with our second pass and qualifying scheduled for tomorrow, today was quite a busy today. During the morning we worked on preparing our car for the track, so that we could make our last practice laps before the single-lap time trial. We were inconvenienced by one of our telemetry radios failing; however, our back-up radios are a different technology that we have used for many miles of testing, so we don't expect this failure to show up again in the future.

After we got Infinium rolling, we were met by Ford Australia's Global Green Challenge Team. Their eco-cars are starting in their respective class of the Global Green Challenge tomorrow, so they came and visited us at the Hidden Valley Speedway so we could meet each other and see each other's vehicles. Their eco-cars side-by-side with Infinium and our support vehicles was quite a sight!

After our quick meeting, it was back to the track to get in more practice laps! Our driver, Sudeep Rohatgi, has been able to achieve consistently faster laps each day, putting us in a good position relative to our competition. We did lose some time on the track after Infinium suffered a flat tire after going over a patch of grass. However, after getting back into the car, Sudeep was able to achieve a time that would have challenged for pole position in 2007--quite a feat for a car carrying 25 extra kg of batteries compared to the competition.

At the end of the day, we rolled Infinium through the garages and out into the track's parking lot. Once in the parking lot, we set up Infinium's concentrators for an evening charge to further test the system. We received quite a crowd of onlookers--many competing teams were curious about the system, of course. We will be testing the system once again tomorrow for sunrise, then making final bolt-checks before our qualifying run. While Infinium was certainly not designed to be the fastest car around the track, we are very pleased with its track performance so far, and hope that our qualifying result will set us up well for the race.

UMSolar and Ford Australia

In order to meet the challenges of transporting our 20-person Race Crew and many of our spare parts across Australia, the Solar Car Team requires a fleet of versatile vehicles for its race caravan.  The University of Michigan team would like to thank Ford Australia for supporting the team by lending us four vehicles that satisfy even the toughest of the race's demands in the upcoming Global Green Challenge.

During the afternoon of September 18th, Ford Australia hosted the team at its Head Office in Melbourne. Infinium and two of the four vehicles Ford Australia provided to the team were on display outside of the Head Office, and we had the pleasure of meeting with many Ford employees. Ford Australia's President and CEO, Marin Burela, joined us to see the solar car and to wish us luck in the Global Green Challenge. Mr. Burela, who previously oversaw Ford's small cars operations globally, spoke excitedly about the Ford Fiesta and Ford's other fuel-efficient vehicles that will be taking part in the Global Green Challenge's eco-car event. Our team is looking forward to competing alongside the consumer vehicles entered into the challenge.

Of the four vehicles Ford Australia is providing to the team, the Ford Territory SUV is a perfect fit for the needs of our Lead, Chase, and Weather vehicles. With three rows of seating, each Territory can carry either seven passengers or five passengers with ample room for extra equipment.  The 30 storage compartments in each car provide plenty of space for any spare parts or tools we may need. Our Chase vehicle even has an LCD screen mounted to the ceiling, so our strategists will be able to use the screen to display telemetry data coming from Infinium. The last of the four support vehicles, Scout, is a Ford Ranger pickup capable of hauling a large cargo load plus a full cab of team members. With these quality vehicles and the generous support from Ford Australia, our team caravan is well-prepared to respond to the challenges we will face in the outback.

In Adelaide

Greetings from Adelaide, South Australia, where the team will call home while we prepare for next month's Global Green Challenge. Last week, our team left Michigan for the 10,000 mile journey to Australia. After some time spent overcoming jet-lag and moving our equipment through international customs, we have settled in to our workspace-away-from-home at Prince Alfred College (PAC) in Adelaide. We are grateful once again this year for the support of PAC, which has provided us the facilities in which we can work as a team. It is great to be reunited with all of our friends and supporters in Adelaide, and we are surely looking forward to the rest of our stay here.

Our arrival in Adelaide reminds us of how far we have come, and we must thank all of those who have allowed us to achieve so much. The efforts of all of our team members, advisors, faculty members, sponsors, friends, families, and other supporters have all been instrumental in the creation of Infinium.

Testing Continues: On the Road with Infinium

Posted Wed, 07/15/2009 - 3:53pm by jfed

Coming off our 2008 victory, we have learned that every mile driven on Infinium before the race is one less mile we are likely to break down on the race. Reliability is essential to building a championship solar car, as well as allowing for ample time to make minor tweaks that translate into minutes off the clock.

As of now, Infinium has driven for over 1080 miles (1738 kilometers) and 26 hours with an average speed around 40 mph (65 kph). We have tested the car through a variety of different scenarios: low speed endurance, high speed endurance, precision steering and handling, basic vehicle dynamics, cobblestone road, and open road during rush hour. I am happy to say that with the exception of a few very minor glitches, the car is performing exactly as designed. We also pass all mandated vehicle dynamics testing for both the 2009 Global Green Challenge and the 2010 North American Solar Challenge with a sizable safety factor. In fact, everyone who has driven the solar car attests that it handles significantly better than the vans that serve as our lead and chase vehicles.

Design to Fabrication: How Infinium's Plugs Get Made

Posted Thu, 03/19/2009 - 4:31pm by jfed

The design-build process our aerodymanics team engages in to produce the car is fairly straight forward.  Once World Solar Challenge regulations were released, our entire engineering division quickly poured over every single regulation.  A variety of different aerodynamic configurations were modeled in Unigraphics NX 5.0 and later analyzed in Fluent to determine coefficients of drag.  At the same time, the Mechanical Division determined the respective weights of all the components in the vehicle to understand their impact on the vehicle's center of gravity as well as the track and wheel base of the car dictated by the aerodynamic shape to determine the ultimate stability of Infinium.  Once the vehicle was determiend to be stable, the Strategy Division took the various coefficents obtained from Fluent, ran vehicle simulations, and the team settled on a body design for Infinium.  

On the path to producing the best car possible, our team is very priveleged to work with some of the best companies in the world.  The model we create in Unigraphics is a meer shell of the car and nowhere close to being manufacturable.  This is the point where Eicher Engineering Solutions steps in.  Eicher Engineering Solutions takes the vehicles body, sections it into each individual component (fairings, upper surface, lower surface, etc.), adds thickness, and refines the aerodynamics.  They are able to do a large amount of the technical work that our team is unable to do.
