Is Finite Element Analysis on your radar for projects you plan to develop during 2019? If not, it should be.

What It Is Finite Element Analysis

Finite Element Analysis (FEA) is an engineering technique used to obtain “approximate solutions of boundary value problems.” By running the specs of your prototype through FEA software, technicians are able to determine strengths, weaknesses, and potential refinements. 

CAFE Standards Continue to Fluctuate

CAFE Standards Continue to Fluctuate

Since the initial establishment of CAFE standards in the 1970s, periodic changes have been instituted to accommodate for growth, industry changes, and new information. As with most changes, each announcement has been met with a wide variety of reactions, from sharp criticism to fawning praise. The government’s most recent announcement has been no exception to this.

Is the Pressure to Meet CAFE Standards Rising or Falling?

Is the Pressure to Meet CAFE Standards Rising or Falling?

Are CAFE standards rising or falling? If we know one thing about American policy and lawmaking, it’s that nothing stays static forever. Over the past centuries of our country’s history, we’ve enacted laws, rolled them back, and reenacted new ones in their places. This is the shape of progress: sometimes we must take a step back in order to take new steps forward.

Most private citizens are unaware that current CAFE standards exist, let alone what they mean and how they impact our society. That doesn’t mean that the average person remains unaffected by them, though.

Before we get to specifics, however, let’s consider what CAFE standards actually are and what they’re intended to accomplish.

CAFE Standards Help Save Money All Around. Much has been written in recent days about the state of the U.S. economy. While we are certainly not a poor nation, if we compare ourselves now to ourselves in days gone by, we’re not doing as well as we have in the past.

According to Financial Timesalthough things are picking up, the economy continues to under perform.

[Gross] domestic product is sluggish, productivity growth is down and, though wages are ticking up, incomes have hardly budged.

But our situation is not hopeless.

In a world where more and more emphasis is being placed on leaving fewer carbon footprints, fuel economy has become an important issue for auto manufacturers across the country. Not only are auto manufacturers attempting to meet the demands of more environment-conscious consumers, they are also trying to avoid paying large sums of money for stiff penalties by complying with Corporate Average Fuel Economy Standards.

CAFE Standards:

The Corporate Average Fuel Economy standards (CAFE) standard enacted in 2014 imposes fuel efficiency and green house gas emission standards on the manufacturers of cars and medium and heavy-duty trucks. These standards get progressively stricter every year, with costly fines imposed for every car or truck model that fails to meet them. Cars must improve performance by 37% and trucks by 23% every year.

Generally speaking, automakers have been beating the CAFE standard every year. It’s in the interests of the manufacturers to build lighter and more efficient vehicles while maintaining high safety standards. How do the manufacturers manage to do that? The goals are achieved by improving engine and transmission technologies, body aerodynamics that reduce air resistance at high speeds, tires with lower rolling resistance, and very importantly parts that reduce weight.

Weight reducing manufacturing technologies:

  • Hydroforming technologies can shape aluminum, brass, steel and stainless steel into complex, hollow forms which are lightweight and structurally stiff and strong.
  • Hydroformed parts eliminate most of the heavy welding required in conventional parts assembly.
  • Using hydroforming technology in manufacture produces structures with fewer separate parts and fewer heavy welds and joints.
  • Hydroforming uses dies capable of high precision, able to meet the exacting tolerances of aircraft parts.
  • Replacing sheet metal bending and joining with hydroforming eliminates multiple welds and draw marks produced by the traditional method of pressing a male and female die together.

A typical example of the benefit of hydroforming is cited by Professor Muammer Ko, of the Virginia Commonwealth University.  Prof. Koe talked about an aluminum radiator support for a passenger car.

  • The stamped manufacture process requires 17 unique parts weighing a total of 16.5 kilograms.
  • The hydroformed part is comprised of 10 parts and weighs 11.5 kilograms (a 30% weight savings).

The hydroforming process can produce structurally stiff and stable parts out of materials that are lighter in weight but able to replace stamped parts made with heavier materials.

  • When an aluminum part replaces a steel or cast-iron part, it means a weight reduction of 40% to 60%.
  • Warm hydroforming greatly increases the formability of lightweight materials like aluminum and magnesium, greatly increasing the possible range of hydroformed parts manufacturing.

Although stamping and welding have not gone away, increasing proportions of the automotive production has gone to hydroforming.
