Noise and Vibration Conference & Exhibition

Raymond Kach, Ph.D., started working at the Ford Motor Company in 1979 in engine simulation after receiving his master's in mechanical engineering. Kach received his Ph.D. in 1988. He spent 12 years working in the Ford Research Labs and 28 years working in Product Development. Kach has over 30 years of experience in engine modeling using 1-D engine performance tools. Kach was involved with the development and implementation of the original 1-D engine performance simulation software that accounts for pressure wave dynamics in the intake and exhaust systems to drive engine performance and exhaust/intake NVH. Based on exhaust system test data, Kach developed new methods to account for the temperature drop along the exhaust system, flow losses across a muffler and catalysts, as well as the impact of the catalyst on pressure waves and flow losses. As the 1-D Engine Modeling capabilities developed, Kach worked with the Air Induction Team at Ford to start incorporating the use of 1-D engine performance analyses into the design of resonators for NVH. In addition, Kach worked with the exhaust system suppliers in the use of 1-D engine performance software for exhaust system design. Kach has been co-organizing the powertrain Intake/Exhaust NVH session since the 1995 SAE Noise and Vibration Conference.   

Presentation Title: The Sound of Synergy

John Maxon is the manager of Acoustics, Vibration, and Community Noise Engineering for Gulfstream Aerospace Corp. Maxon joined Gulfstream in 2004 as a technical specialist after working for Gulfstream’s parent company, General Dynamics, for more than 18 years. While there, he specialized in structural acoustic and vibration analysis at Electric Boat, helping to make U.S. submarines undetectable. He introduced the Statistical Energy Analysis (SEA) acoustic and vibration modeling tool to Gulfstream and directed the development of Gulfstream’s Acoustic Test Facility (ATF). Maxon has multiple patents relating to the innovative acoustic and vibration treatments developed for Gulfstream aircraft and has helped engineers in his group secure over a dozen more patents for innovative interior and exterior noise-quieting designs. Maxon graduated from the University of Miami with bachelor’s degrees in both civil and architectural engineering.

 

Dan Russell earned his Ph.D. in acoustics in 1995 from Penn State, preceded by a M.S. in applied physics from Northern Illinois University and a B.S. in physics and B.Mus. in piano performance from Bradley University.  For 16 years (1995-2011) he was a physics professor at Kettering University in Flint, MI, where he taught introductory and advanced physics to all levels of undergraduate students, along with acoustics and vibration courses to junior/senior engineering and physics majors. He developed an acoustics laboratory currently used for faculty and student research projects as well as for an advanced undergraduate laboratory experience in acoustics and vibration.  Since  2011, Russell has been a member of the faculty in the Graduate Program in Acoustics at The Pennsylvania State University, where he teaches graduate-level courses in acoustics and vibration to both resident and distance education graduate students. In addition, he manages the distance education component of the acoustics program, including oversight of the M.Eng. in acoustics online degree program. Russell’s research interests include the visualization of acoustic phenomena using computer generated animations for educational purposes, and experimental research involving the structural vibration of sports equipment (baseball and softball bats, hockey sticks, rackets, etc) and musical instruments. He is active in the acoustics education community, and his website of acoustics and vibration animations  (acs.psu.edu/drussell/demos.html) is known around the world.
