Noise, Vibration and Harshness Engine Mounts and Vehicle Isolators
Short Course Description
This self-paced short course covers the principles, experimental characterization methods and mathematical models of engine mounts and vibration isolators. The source-path-receiver network and transfer function approaches will be adopted with emphasis on problem solving strategies.
Based on the extensive research and development work that has been carried out at Ohio State, the short course, in particular, has been designed to suit the needs of practicing engineers.
Completion of ME7261 and ME7263 or permission of Professor Singh is required.
Upon completion of this course participants will gain knowledge in:
- Mounting system design methods in time, frequency and spatial domains
- Elastomeric and hydraulic mounts; frequency-dependent and amplitude-sensitive mount properties
- Static, dynamic and modal test methods
- Torque roll axis de-coupling concepts for powertrains
- Vehicle models and modal analysis
- Adaptive and smart mounts; case studies
Raj Singh, academy (emeritus) professor of mechanical engineering at The Ohio State University, held the Donald Glower chair for 13 years. He is a senior fellow at Ohio State’s Center for Automotive Research. Singh served as director, NSF I/UCRC Smart Vehicle Concepts Center for 11 years and now directs the Acoustics and Dynamics Laboratory. His research interests are: acoustics, machine dynamics, vibrations, non-linear dynamics and signal processing. Over the past two decades he has directed over $18 million of sponsored research and grant programs. Singh has published over 500 papers and advised 46 PhD and 77 MS students.
