Experiencing virtual products

17.04.2008
An electric car window slides smoothly upward at the press of a button. While power windows are certainly convenient, they can also pose a safety risk.

For instance, if a child puts their hand out the window to wave to a friend, the window must stop moving immediately or there could be serious consequences: Tiny fingers can easily get jammed, or the window's mechanism may be damaged.

For the first time, the Functional DMU project has enabled Fraunhofer researchers to create a virtual product that can simulate the complex interaction between electrical and mechanical components – such as those used for power windows and convertible rooftop systems.

While computer-supported test models have become part of everyday production activities, not all process chain components can be simulated. "The Digital Mock-Up (DMU) is a virtual model that represents a product's structure and geometry. DMU is today’s standard in virtual product development," says Dr. André Stork of the Fraunhofer Institute for Computer Graphics (IGD) in Darmstadt.

Until now, DMU and the associated software tools have only taken product geometry into account. "However, a growing number of the mechatronic components being used today are still not fully represented in virtual test models, although this is precisely what manufacturers urgently need. Discussions with industry partners have shown that these functionalities are what companies want most," Stork points out in explaining the project's background.

"With the help of various software packages, Functional DMU can simulate a mechatronic product's software-related components as well as its electronic and mechanical components. We import the individual components into a complete model. Once this has been done, we can quickly determine whether the components work well together, or whether there are safety issues such as windows that are too thick and heavy, or an engine that is too weak," the specialist says. Close cooperation between mechanics, electronics and software development is particularly important. In addition to the work of IGD researchers, experts from the Design Automation Division at the Fraunhofer Institute for Integrated Circuits IIS, the Fraunhofer Institute for Open Communication Systems FOKUS and the Fraunhofer Institute for Structural Durability and System Reliability LBF have also contributed to the project.

Together, they have developed a Functional DMU framework that can integrate the mechatronic properties of individual components into the simulation, and can also evaluate them. The framework combines a variety of different commercial simulators, such as SimPack, Matlab/Simulink and Dymola. Here, it is particularly important that the behavior of individual components be visualized in real time. There are now demonstrators that show how Functional DMU works. One of these is the virtual power window, which will be on display at the joint Fraunhofer booth at the Hannover Messe (Hall 17, Booth D60). The next project on the scientists' agenda is the simulation of a steering test rig. Here, again, mechanical, electrical and software components work interactively.

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: An energy-efficient way to stay warm: Sew high-tech heating patches to your clothes

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
