DuPont Shows How Collaboration Generates Better Performance, Lower Cost

19.10.2012
DuPont Performance Polymers is featuring an innovative automotive jounce bumper component to show how design, materials and processing can converge to deliver added performance and lower cost.
The featured jounce bumper is part of a vehicle’s shock-absorber system designed to absorb impact and dampen noise, vibration and harshness (NVH).

DuPont, working with a team from Ossberger, capitalized on the flexibility attributes of DuPont™ Hytrel® thermoplastic elastomer and a unique Ossberger blow-molding technology to simplify the component from four pieces that require subassembly to a single piece. This alone significantly reduced cost, size and improved performance.

The featured jounce bumper is part of a vehicle’s shock-absorber system designed to absorb impact and dampen noise, vibration and harshness (NVH).

“Materials are critical in component design and the best results happen when the three primary phases in product development – design, materials and processing - converge,” said Patrick Cazuc, Automotive Director Europe, DuPont Performance Polymers.

Beyond Materials

In developing this component, DuPont worked on design, using non-linear Finite Element Analysis (FEA) techniques and specialist software, as well as processing, including rapid prototyping and laboratory testing at the DuPont European Technical Centre. By using an Ossberger machine, the thickness profile was tightly controlled, facilitating optimum energy-absorbing properties with a maximum compression ratio.
Proven Performance

These jounce bumpers made of Hytrel® have been tested by automakers on a variety of vehicles over tens of thousands of kilometres. According to an independent vehicle testing institute: "Jounce Bumpers of Hytrel® bring higher comfort and steering feedback, together with better road handling compared to PU (polyurethane) parts. Wheel rebound is also reduced with higher attenuation of low impacts. The front axis roll angle is also reduced."

“The new Jounce Bumper is an example of DuPont listening to market needs and developing a superior solution, while providing all the necessary collaborative support needed to bring an idea from design to commercialisation,” Cazuc concludes. “More to come on this new development.”

Im Focus: Hannover Messe 2015: Saving energy with smart façades

Glass-fronted office buildings are some of the biggest energy consumers, and regulating their temperature is a big job. Now a façade element developed by Fraunhofer researchers and designers for glass fronts is to reduce energy consumption by harnessing solar thermal energy. A demonstrator version will be on display at Hannover Messe.

In Germany, buildings account for almost 40 percent of all energy usage. Heating, cooling and ventilating homes, offices and public spaces is expensive – and...

The IPH presents a solution at HANNOVER MESSE 2015 to make ship traffic more reliable while decreasing the maintenance costs at the same time. In cooperation with project partners, the research institute from Hannover, Germany, has developed a sensor system which continuously monitors the condition of the marine gearbox, thus preventing breakdowns. Special feature: the monitoring system works wirelessly and energy-autonomously. The required electrical power is generated where it is needed – directly at the sensor.

As well as cars need to be certified regularly (in Germany by the TÜV – Technical Inspection Association), ships need to be inspected – if the powertrain stops...
