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.

Course main content

Review of current methods for the noise, vibration and harshness (NVH) design of passenger vehicles. Load cases, analysis types and CAE (Computer Aided Engineering) optimization processes.
