Song He (Presidential Fellow) Wins the Best Student Paper Award at National Conference on Noise Control

Song He (ME doctoral student and Presidential Fellow, from Professor Raj Singh's Acoustics and Dynamics Laboratory) has won the Best Student Paper at the National Conference on Noise Control Engineering (NOISE-CON 07, Reno, NV, October 22-24, 2007). The award criteria evaluated the difficulty of the problem addressed, the practical value to noise control engineering, and qualities of the investigation, technical communication and oral presentation. Song's award-winning paper, entitled "Improved Gear Whine Model with Focus on Friction-Induced Structure-borne Noise", is co-authored with Prof. Raj Singh (OSU) and Prof. Goran Pavic (INSA Lyon, France). This paper proposes a refined source-path-receiver model to quantify the effect of sliding friction on gear noise. This work was funded by the Army Research Office, Presidential Fellowship from the Graduate School (OSU), and European Commission’s Marie Curie Fellowship (INSA Lyon), and experiments were conducted at NASA Glenn Research Center.

Song He (ME PhD Student) Awarded the 2007 Presidential Fellowship by OSU Graduate School

ME doctoral student Song He (advisor: Prof. Raj Singh) has been awarded the Presidential Fellowship by the Graduate School in Spring 2007 competition. This prestigious fellowship recognizes outstanding scholarly accomplishments and potential of graduate students entering the final phase of their dissertation research. Recipients of this award embody the highest standards of scholarship in our graduate programs. Song's doctoral research will characterize the effect of sliding friction on the dynamic behavior of spur and helical gears. Previously, he was awarded the Marie Curie Host Fellowship of the European Commission (EC). from January to June 2007. This allowed Song conduct research at the National Institute of Applied Sciences (INSA) in Lyon, France.

Alumnus Dr. Todd Rook Receives the 2006 Dean's Meritorious Service to Students Award

Dr. Todd Rook, a mechanical engineering alumnus, recently received the Dean's Meritorious Service to Students Award for 2006. This award recognizes an individual outside The Ohio State University community for exemplary service to students of the College of Engineering or the Knowlton School of Architecture.

Graduating with B.S.M.E., M.S.M.E., and Ph.D degrees from OSU, Dr. Rook is the Lead Analytical Development Engineer at the Aircraft Wheels and Brakes division of Goodrich Aerospace. His work includes advancing predictive modeling capabilities to aid in the integration of brake and landing gear systems. His research focuses on noise reduction, numerical techniques for nonlinear dynamics, and structural/acoustic intensity.

Dr. Rook has enriched the education of mechanical engineering students at OSU by mentoring undergraduates in capstone projects, while providing them with "real-world" design experience. He has provided guidance to graduate students whose research efforts have been published in academic journals, and he frequently gives presentations on ABET-related issues.

The Mechanical Engineering Department congratulates alumnus Dr. Todd Rook for his distinguished career with Goodrich Aerospace, and for receiving the 2006 Dean's Meritorious Service to Students Award.

Dr. Singh is Elected as a Fellow of SAE

Dr. Rajendra Singh, a Professor in the Mechanical Engineering Department and the Director of the Acoustics and Dynamics Laboratory, has been elected as a Fellow of the Society of Automotive Engineers (SAE).

Dr. Singh's Fellow status reflects his significant impact on the field of engineering, and his outstanding contribution to vehicle noise and vibration control research and education.

Dr. Singh has pioneered new mathematical models of powertrain and driveline systems and vehicle components, while proposing improved dynamic design procedures. He has developed innovative graduate courses in vehicle noise, vibration and harshness (NVH) control, and he has been elected to fellow-grade memberships in other prestigious societies, including the Acoustical Society of America and the American Society of Mechanical Engineers.

The Mechanical Engineering Department at the Ohio State University congratulates Dr. Rajendra Singh for his outstanding achievements in the field of vehicle noise and vibration control, and for his election as a Fellow of the Society of Automotive Engineers.

Two OSU Researchers Win Prizes at the SAE Noise and Vibration Conference

Ashley Crowther

Song He

Two students from Professor Raj Singh's Acoustics and Dynamics Laboratory (of the Dept. of Mechanical Engineering and the Center for Automotive Research) won the research awards at the recent SAE Noise and Vibration Conference (May 16-19, 2005).

Ashley Crowther, a visiting scholar from UTS Australia, was awarded the first prize in the student poster competition for his doctoral research in "powertrain vibration". Ashley will receive his PhD degree later this year. Song He won the third prize for his Master's degree work on the "Inclusion of quasi-linear hydraulic engine mount formulation in vehicle models".

This conference is a premier event in noise and vibration technology as over 1,100 experts and practitioners from around the world attended the conference. Overall, the OSU Acoustics and Dynamics Laboratory presented the most papers including 6 research articles and two student posters. All presentations were well received by the automotive industry, and collectively they illustrated the research achievements and strengths of the Laboratory.

Two papers, as presented on the research of Ashley Crowther and MS student Wansoo Oh, included predictions of transient gear impacts in vehicle drivelines, covering non-linear simulations in both manual and automatic transmission configurations and introducing quality metrics to evaluate impulses. Another paper on the stick-slip behavior of an automotive clutch summarized the elements of doctoral research by Dr. Chengwu Duan. This fundamental research characterizes the non-linear behavior in torsional systems with friction as the dominant path under the presence of both mean load and harmonic excitations. Research into the structure-borne noise transfer paths by Dr. Seungbo Kim (currently at the Goodyear Technical Center) and PhD student Akira Inoue was presented as well. Using experimental methods, they illustrated the rank orders of three parallel structural paths. Finally, Song He, now a PhD student, presented two papers on nonlinear models and identification of hydraulic engine mounts. One paper addressed low frequency and transient response issues and the other one analyzed the higher frequency models.
