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.

Goals

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
