Prof. Monika Ivantysynova Wins the Purdue Morrill Award!

We would like to congratulate Prof. Monika Ivantysynova as one of the three winners of the 2016 Morrill Award along with Douglas Powell and Phillip Wankat! The three winners were announced yesterday at the Faculty Awards Convocation. The Morrill Award was initiated five years ago to honor the Morrill Act of 1862 which established land-grant colleges and universities. Prof. Ivantysynova was honored with the award for making significant contributions in each of the university's mission areas and for her advancement of the field of fluid power. The official announcment on Purdue's newsroom says the following about Prof. Ivantysynova's accomplishments.

"Ivantysynova's research in the field of modeling and simulation of pumps and motors has led to several new discoveries about the fundamental behavior of fluid film and its importance for the design and successful operation of positive displacement machines. Her findings permit advances in the design of current hydraulic actuation systems used in agriculture, construction, aerospace, marine, and industrial machines, resulting in reduction of fuel consumption, improved reliability, reduction of noise emissions, and even a reduction in system cost due to reduced mechanical complexity.

Several industry sponsors have commercialized her inventions, including a novel concept for hydrostatic transmission that includes energy recovery features now used in the garbage trucks commercialized by Parker Hannifin. In 1999, she was one of the founders of Fluid Power Net International, the first international scientific network in this field.

Ivantysynova established Purdue's Maha Fluid Power Research Center, which focuses on ways to save energy through hydraulic systems. Under her leadership, the center has organized and hosted the Research Experiences for Undergraduates Bootcamp of the NSF Center for Compact Efficient Fluid Power, providing an introduction to fluid power for undergraduate students from various U.S. universities."

Maha's Andrew Robison Awarded the NSF Graduate Research Fellowship!

We would like to congratulate Andrew Robison, who was awarded the prestigious NSF Graduate Research Fellowship based on his "demonstrated potential to contribute to strengthening the vitality of the U.S. science and engineering enterprise." Andrew started his Ph.D. studies last August studying noise emissions of geroter pumps under the advisorship of Prof. Andrea Vacca. He has been a great addition to the team. Congratulations Andrew!

Congratulations to the Chainless Challenge Team!

We would like to congratulate Purdue University's Chainless Challenge team for their success at Parker's Chainless Challenge Competition last week in Irvine, CA. Various teams from across the nation designed and built their own versions of fluid power driven "bicycles" that they then presented and competed with at the event in Irvine. More information about the chainless challenge and a recap of last year's competition can be found here.

The team placed first in three of the event's competitions, second in two more, and second overall in the overall success and presentation of the bike. This year's team consisted of Riccardo Bianchi, Matteo Foa, Trevor Overstreet, and John Bowis under the direction of Prof. Andrea Vacca as the team's advisor. However, the team owes much of its success to Maha's very own lab manager, Anthony Franklin, who coordinated the manufacturing of the vehicle and lead the team at the final event. Below are pictures of the team and their bike at the competition.

Welcome New Maha Team Members!

We would like to extend a very warm welcome to the following new members of the Maha team:

Visiting Researchers

Dr. Tatiana Minav and Philipp Wagner are visiting Maha for the next few months and will be working with Prof. Monika Ivantysynova's group. Philipp is visiting us from the Graz University of Technology and will be helping with our ongoing noise research in Prof. Ivantysynova's pump group. Tatiana is visiting from Aalto University and will be splitting her time between the pump and systems groups.

Federico Campanini is visiting Maha from Universitá Degli Studi di Parma and will be working with Prof. Andrea Vacca's systems group on the mobile crane.

Contratulations to Dr. Timothy Opperwall and Dr. Guido Ritelli on Successful PhD Defenses!

We are pleased to announce that Tim successfully defended his Ph.D. dissertation on November 30, 2015 and Guido successfully defended his Ph.D. dissertation on December 7, 2015!

Tim has been a key member of Prof. Vacca's external gear pump modeling group for the past five years. His research was focused on reducing the noise of hydraulic components and systems through both modeling and experimental approaches. Tim will be going to work at Husco International in Milwaukee, WI. His leadership and contributions to the team will be missed.

Guido has worked in Prof. Vacca's systems group since February of 2012 on payload oscillation damping of a hydraulic truck loading crane. The next exciting chapter for Guido is in joining Artemis Racing in Bermuda. We will all miss Guido's insightful comments and feedback in our Maha Seminar series.

We wish both Tim and Guido the best in the next stage of their careers!

Congratulations to Dr. Michael Sprengel on a Successful PhD Defense!

We are pleased to announce that Mike successfully defended his Ph.D. dissertation on November 10, 2015! Mike has been an integral and productive part of Prof. Ivantysynova's hydraulic systems research group since August of 2010. In his time at Maha, Mike has developed a novel hydraulic hybrid transmission architecture and helped to implement it on the Maha Hydraulic Hybrid Range Rover. Mike has also developed improved dynamic programming routines for analyzing hydraulic transmission architectures and exploring optimal transmission component sizing parameters. His work will lead to more efficient hybrid systems and a more widespread realization of on-highway hydraulic hybrid vehicles.

The Maha team will miss Mike and his contributions to the lab and wish him the best as he moves forward with his career. Mike will be starting as an Engineer/Analyst at Czero in Fort Collins, CO, in January.

See the Maha Hydraulic Hybrid Vehicle Driving!

We would like to congratulate the research team that has done such a wonderful job on developing the world's first on-highway hydraulic hybrid SUV one more time. The team has made continued progress since our initial announcement that the converted Range Rover is running. Thanks to their efforts and the generosity of our sponsors, this vehicle will be a source of many theses and papers for the lab for years to come in addition to the publications that it has already generated. We would also like to thank Eight38 Graphics for the great new look.
