Racing time and money to build a fast car

It's a race to finish, and to find finances for ASU's Formula SAE team.
It ain't cheap building a race car; just ask these ASU students.

ASU student-led Formula SAE team finding finances to be the biggest hurdle

Editor’s note: This is the latest installation in a yearlong series about ASU's Formula SAEFormula SAE is a student design competition organized by the International Society of Automotive Engineers (now known as SAE International). team. Read the first story here.

If the Arizona State University engineering students building a Formula-style race car wanted a challenge, they’ve got a hefty one in front of them trying to make the deadlines to get it into the national competition in June.

For the design, management and costs of building this SDM-15 (Sun Devil Motorsports) racer, they’re on their own. Two of those three aren’t a problem.

Like so many things in life, the biggest issue they’re facing is financial. The racer will cost about $38,000 to create.

“Our theme is that we’re low on money,” said team manager Troy Buhr. “As of this moment we have $600 in the bank.”

For perspective, tires can cost more than $400 each. Racing engine control units can cost well more than $1,000. And the costs go on and on.

“I think the main idea is we know what we want to do, but as soon as we get the money we spend it,” said chief engineer Wes Kudela.

To help solve that problem, the members of ASU's Formula SAE team — made up of students in the Ira A. Fulton Schools of Engineering — have learned what the business world knows so well: When there’s a problem you can’t handle, call in consultants.

The team has recruited five students from the W. P. Carey School of Business majoring in subjects like business management. The business majors meet weekly with the engineers.

“It’s awesome to have them in here,” Buhr said. “They think completely differently than us. It’s young right now, but I like the way it’s going.”

“A lot of them love cars.”

Building the SDM-15 is a quest for a simplistic car that is durable and handles well. They want it to be lightweight but stiff in the chassis, braking system and suspension.

“The build is going great,” Kudela said.

And managing the project is going smoothly. The goal to have all 110 team members involved as much as possible is progressing well.

“We’re seeing 50 to 60 guys come in and get their hands dirty every weekend,” Kudela said.

“We’ve never had this much momentum, and it’s good to see people excited,” said team captain Pranav Mamidi. However, he said, “we’ve always lagged in the business department.”

Raytheon donated $2,000 to the Ira A. Fulton Schools of Engineering, but it had to be split with the SAE Aero Design team. Tempe-based Trimble Consulting Inc., a technical, business and educational services consulting company, donated $750. Ford Motor Company gave $2,500. “We showed them the chassis and the shop, and they were impressed,” Mamidi said.

Team members are talking with possible sponsors including Chrysler, Avnet and Boeing. “We’ve also been compiling a list of potential local sponsors,” said Mamidi, referring to businesses such as car dealerships.

One of the engineering challenges is balancing structural integrity with weight.

“We know we’re going to be testing really hard,” Kudela said.

The base rails on the chassis are perfectly straight, which is important because everything else goes on top of them. The team doesn’t have a fixture table, which is perfectly flat and used in welding and assembly. “We have to spend a lot of time getting the chassis straight on it,” Kudela said.

The chromoly tubes have been tacked together, but not yet fully welded. The car will flex when it’s eventually built and unclamped from the table. Because heat from welding can deform metal, it could create a crooked car, so the chassis will be fully welded later.

The computer-aided design model has been completed. The pedals have been designed. The team has chosen a foot clutch instead of a hand clutch because it will be more natural to drive.

“We are working on designing a steering rack,” Kudela said. A manufactured steering rack won’t be ready by their January goal to complete the car. Last year they literally finished the car in a parking lot in Lincoln, Nebraska, where the national competition is held. This year they want the car completed in January so they can test and improve it.

The team has also decided to use braided brake lines. Hard brake lines are more durable. Braided brake lines are easier to route through the car, but they flex under pressure. To justify using them, they had to prove the braided lines don’t deform or move under the pressures they’re using. So they tested the lines and proved them acceptable. That’s one type of detail they will be judged on at the national competition in June.

“We want to build from a durability standpoint,” Kudela said.

The team needs to purchase an engine control unit, a small computer that optimizes engine performance. Like most of what they need, the unit can’t be found at a local Auto Zone store. It has to be purchased from a specialty vendor.

They are working on the aero kit, calculating cooling capacity of the radiator in a carbon fiber side pod. If the hole in the front of the side pod is big, it cools the engine down a lot more, but it also slows the car down. “We’re doing extensive calculations on that,” Kudela said.

There is some debate about one radiator side pod vs. two. A car with two side pods will look more balanced, but “sometimes asymmetry can be cool,” Mamidi said.

This isn’t a go-kart being built; it’s a four-cylinder engine Formula-style car, and it’s going into national competition where the big automakers will all have scouts watching.

Future jobs are on the line here.

3 ASU students finalists for prestigious scholarships

November 4, 2015

Three Arizona State University students are finalists for three prestigious international scholarships. The three students are Annie Carson, a finalist for the Marshall Scholarship; Michael Meaney, a finalist for the Mitchell Scholarship; and Jessica Hocken, a finalist for the Schwarzman Scholarship.

The Marshall Scholarship provides the opportunity for 40 students in the United States to receive an advanced degree in the United Kingdom. If Carson is awarded the scholarship, she will pursue a Master of Arts degree in philosophy, politics, and economics of health at University College London, followed by a Master of Science degree in reproductive and sexual health research at the London School of Hygiene and Tropical Medicine. Carson hopes to become a leader in global maternal health care research and policy.

Michael Meaney is a finalist for the Mitchell Scholarship. The Mitchell Scholarship pays for students to earn a master’s degree in Ireland. Meaney graduated from the Mary Lou Fulton Teacher’s College at ASU with a master’s of secondary education. He currently is a manager of Education and Workforce Innovation in the Office of the President at ASU. If selected, Meaney will pursue a Master of Science degree in education and training management at Dublin City University.

Jessica Hocken, a senior in the W. P. Carey School of Business and Barrett, the Honors College, is a finalist for the Schwarzman Scholars Program. The Schwarzman Scholars Program supports one year of graduate study at Tsinghua University in China. If selected, Hocken would be part of the inaugural class of Schwarzman Scholars.
