Noise, Vibration & Harshness I (ME7261)
Noise Vibration and Harshness I (NVH I) is an integrated study of vibrations, acoustics, digital signal processing and machinery dynamics based on case studies; examination of design, manufacturing, material, performance and economic considerations.
This 4 credit-hour graduate course, the first in the NVH series, uses an innovative case study approach. A 3 credit-hour course (ME7260) is also available. Weekly lectures are supplemented with bi-weekly group discussions on key NVH issues. A course project on a contemporary topic is required.
A bachelor’s degree in mechanical or electrical engineering is required.as well as completion of the Mathematical Prep seminar or permission of Prof. Raj Singh.
Upon completion of this course participants will be able to:
- Apply acoustic, vibration and harsness design criteria (sound quality, source-path-receiver concepts and applications) to vehicle problems
- Create mathematical models and computer simulations (input-system-output paradigm, frequency response functions and system parameters)
- Perform vehicle modal analyses: (eigenvalue problems, modal domain properties, identify vehicle noise and vibration sources)
- Calculate frequency response and vibration control: vibration absorber concept and vehicle applications
- Understand vibration and noise path control elements (isolation, damping, balancing, resonators, absorption, barriers and enclosures)
