Content and learning outcomes
Course contents
Intended learning outcomes
The goals of the course, for the student, are:
- To understand the basic principles of the design aspects for NVH in cars.
- To know the most dominant sources of noise and vibration in cars, the dominant transmission paths including their relative importance at different driving conditions.
- To understand the critical design issues and their relations for NVH, in particular the aspects of objective and subjective design.
- To get a basic knowledge in the process driving concurrent design, in particular in view of vehicle acoustics.
- To get an overview of state-of-the art in Computer Aided Engineering applied to NVH together with examples of NVH issues treated by CAE and to understand the limitations of the models used.
- To get a basic understanding of the difference between objective and subjective (human response) design criteria and how they influence the design process.
- To get an overview of modern design solutions in NVH, the materials used and their principle function, together with the current trends in the development of new solutions.
