Congratulations to Xiaofan Guo (Parker) on his Successful Master's Defense!

We would like to congratulate Xiaofan Guo (Parker) on his successful Master's defense on September 18, 2017! Parker joined Maha in November 2015 and has worked as part of Prof. Ivantysynova's systems' group. For his Master's research, Parker developed a novel displacement controlled steer-by-wire system for mobile machinery. He demonstrated the significantly improved performance of this system using validated simulation mdoels of a combine harvester steering system.

We are pleased that Parker will continue at Maha towards a Ph.D degree and look forward to his future research discoveries!

Congratulations to Yash Shah and Srinath Tankasala on Successful Master's Defenses!

We would like to congratulate Yash Shah and Srinath Tankasala on their successful Master's defenses on July 13, 2017! They have both been integral members of Prof. Vacca's pump group for the past two years.

Yash joined Prof. Andrea Vacca's pump modeling research group in August 2015 and has contributed towards developing novel cavitation modeling approaches for Fluid power systems. His research focused on the development of dynamic cavitation model that accounts for compressibility effects of multiphase flow and non-equilibrium effects of phase change in terms of physically realizable parameters. Yash is heading to Penn State University for a Ph.D. in Mechanical Engineering.

Srinath began working in Prof Vacca's pump group in August 2015 as well and built on the work done by the group on variable displacement gear pumps. His research focused on optimizing the design of a low pressure variable delivery gear pump. He demonstrated the design concept with a fabricated prototype that was tested at Maha. Srinath leaves Maha to join The MathWorks in Boston.

We wish both of them great success in the next stages of their careers!

Purdue team wins the 2017 NFPA Fluid Power Vehicle Challenge!

Congratulations to the team of students that won the 2017 Fluid Power Vehicle Challenge organized by the National Fluid Power Association (NFPA). The annual competition is open to US engineering schools with a fluid power program, and this year, the students representing Purdue University emerged as winners, competing against strong teams from UIUC, Ohio State, Western Michigan State, among many others.

The Purdue bicycle is fast (>30 km/h) and is capable of recovering energy while braking by utilizing a carbon-fiber accumulator. One of the bicycle’s innovative features is the use of its lightweight aluminum frame as a reservoir. The bike uses Electro-Hydraulic technology and is fully controlled by a smart-phone app. The app can also monitor the heart rate of the rider and displays the hydraulic system parameters in real time, including instantaneous efficiency!

The team won the overall competition, excelling in all sub-categories:
1st in Reliability Race
1st in Best Design
1st in Efficiency Challenge
2nd in Endurance Race
2nd in Best Paper & Presentation
3rd in Manufacture
3rd in Sprint Race

In the picture below, the Purdue team is shown after returning from the competition in Ames, Iowa at Danfoss. (April 19-22, 2017): Gianluca Marinaro (team leader) , Zhuangying Xu, Chenxi Li, Zhengpu Chen, Yizhou Mao with the team advisor Dr. Andrea Vacca.

Congratulations once again!!

Congratulations to Dr. Taeho Kim on a Successful Ph.D Defense!

We would like to specially congratulate Dr. Taeho Kim on his successful Ph.D. defense on April 12, 2017. He began his studies in Prof. Ivantysynova’s pump group in August of 2012 and has contributed greatly to the success of the group during his time here.

Taeho’s research focused on developing the swash plate active vibration control for axial piston machines and investigating the effect of swash plate vibration reduction on pump noise emissions. He has developed high-bandwidth pump control systems and demonstrated the feasibility of swash plate active vibration control and active noise control.

We will miss Taeho's contributions as a member of the Maha team and wish him all the best in his future career.
