Maha Welcomes CCEFP Bootcamp Students

The 2013 CCEFP Fluid Power REU Bootcamp was held at Purdue University on May 29-30, 2013. Undergraduate students from various U.S. universities joined the Center’s universities (Georgia Tech, University of Illinois in Urbana-Champaign, University of Minnesota, Milwaukee School of Engineering, North Carolina A&T State University, Purdue University, and Vanderbilt University) to perform research in fluid power during the summer period.

A crash course was designed to teach the students the fundamental principles of hydraulics and pneumatics. The program started by an opening address by Prof. Monika Ivantysynova about fluid power in general and then a lecture entitled "Introduction to Fluid Power Systems" by Prof. Andrea Vacca. The students attended the following lectures / demonstrations:

- "Hydraulic Components Characterization on the Water Hydraulic Test Rig" prepared by Guido Francesco Ritelli

- "Parker Trainer Bench: Motion Control" prepared by Gabriele Altare

- "Pump Displacement Controlled Actuation Technology" prepared by Naseem Daher

The bootcamp was also a great networking opportunity for the participants to meet other students and faculty members in the Center. Below are a few pictures from the bootcamp at the Maha Fluid Power Research Center.

NSF Site Visit of CCEFP at Purdue

This year’s NSF Site Visit of the National Science Foundation Engineering Research Center for Compact and Efficient Fluid Power (CCEFP) took place at Purdue University on April 22-25, 2013.

Part of the NSF Site Visit was a tour of the Maha Fluid Power Research Center. This allowed more than 130 people to tour our lab on Tuesday afternoon. Maha graduate students presented the Maha test rigs and their research projects to the NSF Site Visit team, the Industrial Advisory Board, and all other guests and members of the CCEFP. One of the highlights of the lab tour was a live demonstration of the CCEFP Test Bed 1, the displacement controlled mini excavator with its new hydraulic hybrid architecture for the swing drive. This machine represents the world’s first of its kind.
