Noise, Vibration and Harshness II (ME7263)
This graduate course, the second in the Noise Vibration and Harshness (NVH) series, uses an innovative case study approach to enhance analysis of current NVH concepts and issues. Weekly lectures are supplemented by bi-weekly group discussions on important NVH issues. A project on a current NVH topic is required.
NVH II, a 4 credit-hour course, continues the integrated case study approach of vibrations, acoustics, signal processing and dynamics with focus on experimental and design methods. A 3 credit-hour version (ME7262) also is available.
A bachelor’s degree in mechanical or electrical engineering is required as well as completion of the NVH I course and NVH Math Prep required unless waived by professor Singh.
Upon completion of this course participants will be able to:
- Understand vehicle noise and vibration sources: friction induced sources (complex eigensolutions, driveline judder case study and stability issues, brake sequel, groan and judder case studies); clearance induced sources (design solutions; transmission rattle and vehicle clunk); aerodynamic sources (vortex shedding, vehicle tire, antenna and mirror case studies)
- Conduct modal testing and beam vibrations: material selection issues and boundary conditionsmodal testing procedures; visco-elastic damping and modal radiation
- Apply advanced topics: mobility synthesis method; lumped parameters and 3D acoustic models
- Develop a course project on an advanced NVH topic
