The Maha Hydraulic Hybrid Vehicle Continues to Progress!

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 announcement that the converted Range Rover is running a little over a week ago. 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.

The Maha Hydraulic Hybrid Vehicle is Running!

We are very pleased to announce that the research team here at Maha has successfully developed the world's first on-highway hydraulic hybrid SUV. To achieve this, the Maha team replaced the original automatic transmission in a 1999 Range Rover with a novel blended hydraulic hybrid transmission that was invented by the researchers at the Maha Fluid Power Research Center.

The blended hybrid transmission involves the use of a hydraulic pump and motors to transmit power from the engine to the wheels and includes a hydraulic accumulator for energy recovery during braking. The new transmission allows for better engine management and improvements in fuel economy. These are not the only benefits that this novel hybrid vehicle offers and the Maha team is eager to demonstrate the vehicle's potential to answer today's fuel economy problems and environmental concerns.

We'd like to thank the sponsors that have helped make this accomplishment possible. Many thanks to Danfoss, Hydac, Sun Hydraulics, Durst, Casappa, and ExxonMobile!

Congratulations to Dr. Ram Sudarsan Devendran on a Successful Ph.D. Defense!

We are very pleased to announce that Ram successfully defended his Ph.D. dissertation today. Ram joined the Maha team in the fall of 2010 as a Master's student under Prof. Andrea Vacca. In Ram's time here, he as successfully formulated and demonstrated a working concept for a variable displacement external gear pump.

The Maha team will certainly miss Ram and his valuable contributions to the research done here, but we wish him success as he progresses onto the next phase of his career. Below are a few pictures from Ram's defense and the friendly challenges set for him by his colleagues.

Maha Hosts the 2015 CCEFP IEC Summit

The Center for Compact and Efficient Fluid Power (CCEFP) held the 2015 Industry Engagement Committee (IEC) Summit meeting this past week at Purdue University. More than 60 representatives from 33 companies and more than 30 researchers from CCEFP member universities attended the event. The summit's theme was "High Power and Mobile Applications" and roughly half of the CCEFP research projects and testbeds were presented for the industry supporters who attended. The CCEFP referred to this event on their website as "the best vehicle for driving a close working relationship between US academic fluid power research and industry."

As part of the summit meeting, Maha hosted a wonderful dinner for the attendees after they spent the afternoon touring the Maha lab. During the tour, Maha was pleased to showcase the innovative work taking place on the world's first blended hydraulic hybrid SUV as well as advancements in advanced control strategies for a highly efficient displacement-controlled hybrid excavator that has been developed as a CCEFP sponsored project. Attendees also had the privilege of test-driving the world's first displacement controlled steer-by-wire wheel loader.

Maha Welcomes CCEFP REU Bootcamp Students

The 2015 CCEFP Fluid Power REU Bootcamp was held at Purdue University this past week from May 26-29. The NSF's Research Experiences for Undergraduates (REU) program is designed to encourage STEM students to continue their learning in graduate school settings by providing opportunities for summer experience in a university research lab. The CCEFP is actively involved in this program and hosts at least 14 REU students from its 7 member universities in a bootcamp style introduction to fluid power topics.

This year's bootcamp was a two day introduction to the principles of fluid power technology through various lectures, hands-on activities, and tours of some of Purdue University's research laboratories. Maha's Prof. Andrea Vacca, Ashley Wondergem, Enrique Busquets, Tim Opperwall, Guido Ritelli, and Lizhi Shang were instrumental in providing high quality instruction for the "bootcamp survivors", as they are called on the 2015 CCEFP REU blog.
