Fluid Power Research Aligned With NFPA Technology Roadmap

By Eric Lanke, NFPA President/CEO

I recently had the pleasure of attending the October 2019 Summit of the Center for Compact and Efficient Fluid Power (CEEFP) on the campus of the University of Wisconsin – Madison. Twice a year, the CCEFP puts on one of these summits to present its ongoing fluid power research projects and to facilitate interactions between its academic faculty, graduate students, and industry supporters.

The NFPA Foundation has provided research supplement grants to many of the researchers so they can attend and present at these summits, and this one was no exception. All 11 of this year’s supplement recipients presented at the summit. It gave me an ideal opportunity to align their projects with the research objectives identified on our recently updated Technology Roadmap for the Fluid Power Industry. Doing so helped me better understand which parts of the broad pre-competitive research agenda that our Roadmap describes are being addressed by our growing research coalition. During the summit, I saw projects presented that were clearly targeted at the following Roadmap objectives:

IMPROVING FLUID POWER’S RELIABILITY AND DURABILITY 

Objective: Improve surface finish properties for advanced reliability and durability of fluid power components

Projects:

“Novel Coatings for Advanced Fluid Power Systems,” Osman Levent Eryilmaz, Argonne National Lab

Any NFPA member interested in learning more about any of these projects should contact me at elanke@nfpa.com or (414) 778-3351. I’d be happy to share the PowerPoint presentation from the projects that piqued your interest and/or help connect you with the researchers working on the appropriate advancement.

It was great to see so much alignment with the pre-competitive research objectives identified by our industry.
