A new spin on washing machine design

Do you remember the old washing machine your parents owned when you were a kid?

After mom would load up the washer with the family’s laundry she would turn the big central knob to the on position. From that point on the washer would begin to vibrate, shake, and convulse as it seemingly pulverized our clothes into a state of cleanliness again. The loud thumping of the spin cycle would echo throughout the house as the floor beneath us would vibrate. If wash time began to interrupt dinner or family movie night then I would be sent on a mission down to the basement to stop the bubbly beast mid cycle; only to be started up again when we no longer needed to speak or hear our own thoughts again.

Some of you may still experience the horror … I mean nostalgic pleasure of using a washing machine like this today. But I have since moved on to a much more quiet, efficient and smart machine.

Consumers demand connected, intelligent, almost instinctual electronic products to enable their work and delight their senses. Imagine my new washing machine … it is smart enough to optimize its energy and detergent use. It calculates load weight and detects what kind of clothing is being washed. It runs so quiet, it can be housed anywhere. And because it’s connected, I can control its operation through a mobile device anywhere, at any time.

You may not know it, but today’s innovative washing machine designs, are in part the result of leading technology manufacturers using realistic simulation technology to analyze and improve their designs.

By using simulation and design exploration software, white goods manufactures have been able to simulate virtual product tests while evaluating and analyzing hundreds of design options. It’s interesting to learn how the advances in simulation capabilities and computing resources are enabling washing machine producers to save time and money while optimizing the perfect washing machine design for all our needs.

Dassault Systèmes welcomes Safe Technology!

I’m very pleased to announce that Dassault Systèmes has acquired Safe Technology, Ltd., the developer of the fe-safe durability simulation application suite.

Even if you haven’t used their products, you’ve probably heard the name – Safe Technology has been a partner of ours for over 15 years, providing a fatigue solution to Abaqus users through fe-safe. As an add-on to Abaqus/CAE, fe-safe uses proven techniques to accurately determine the fatigue life of metal components under complex cyclic loading. fe-safe combines finite element analysis results for multiple loading conditions from Abaqus with the cyclic load history to predict the life of the component. Reading from & writing to the Abaqus results files allows the users to view fatigue results in Abaqus/CAE or Abaqus/Viewer as contour plots for damage, fatigue life and safety factors. Similar interfaces are available for many other leading FEA product suites.

In addition to fe-safe, there are several complementary modules available which expand the capabilities of fe-safe to account for specific applications, such as composite materials, creep and  thermomechanics.

Check out this short video tutorial for an overview on fe-safe, and it’s use in solving Fast Gear Fatigue Analysis example.

This technology can (and to a degree, already has) benefit the analyst in the quest for a complete, unified solution to engineering problems. We’re all really excited to welcome our new colleagues and begin our journey to provide an even better 3DEXPERIENCE with this exceptional acquisition in the field of durability & fatigue  :-)

Professor Plum with the Wrench? Abaqus FEA Knows

No, it’s not the famous game “Clue”. It’s the use of realistic simulation to perform forensic studies of skull fracture.

While, for the average person it is a bit gruesome to think about, medical examiners and police investigators are often faced with the need to determine how and why skull fractures occur.

Was the head injury caused by an accident or was the injury caused with the intent to murder the victim?

Researchers at the Institute of Forensic Medicine at the University of Copenhagen, in cooperation with the Technical University of Denmark (DTU), are using using technology from Simpleware (a SIMULIA partner) to transfer CT-scan data into SIMULIA’s Abaqus FEA software.  This allows them to gain a deeper understanding of the mechanics and forces that cause severe skull injuries.

While the researchers consider their current studies as preliminary, these represent a critical step on the path to developing a general tool for supporting medical examiners with easy, achievable and accurate numerical simulation to support their judgment regarding the cause of death.

To get more details, check out the complete case study in the latest issue of INSIGHTS magazine  here.

Are you as surprised as I am that Abaqus FEA software (traditionally used to study the performance of mechanical systems in cars and airplanes) is being used in forensic head injury research?
