Driveline/Powertrain Systems

Short Course Description

Based on extensive Noise, Vibration and Harshness (NVH) research at Ohio State, this self-paced short course examines noise and vibration control methods for vehicle driveline/powertrain components and systems.

Linear and nonlinear models, along with source-path-receiver networks, are employed to characterize and simulate the governing torsional systems.

Completion of ME7261 and ME7263 or permission of Professor Singh is required.

Goals

Upon completion of this course participants will gain knowledge in:

  • Source-path-receiver networks for driveline/powertrain system problems
  • Linear and nonlinear models for torsional systems
  • Excitation mechanisms (engines, gears, etc...)
  • Frequency and time domain responses and their interpretations
  • Nonlinear effects associated with backlash, multi-staged stiffness and dry friction elements
  • Practical case studies including transmission rattle, driveline clunk, clutch judder and gear whine

Faculty

Raj SinghRaj 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.
