Content and learning outcomes
Course contents
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. NVH analysis with relationship to other vehicle function CAE processes. Modeling, analysis procedures and accuracy of results in “virtual“ vehicle development process. Variability in actual vehicle structures. Materials, modeling and design, for NVH treatment. Sound quality. Source identification.
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.

Examination and completion
If the course is discontinued, students may request to be examined during the following two academic years.
Grading scale
Examination
- INL1 - Assignments, 6.0 credits, grading scale: P, F
Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.
The examiner may apply another examination format when re-examining individual students.
Other requirements for final grade
Project assignments (INL1; 6 university credits).
Opportunity to complete the requirements via supplementary examination
Opportunity to raise an approved grade via renewed examination
Examiner
Ethical approach
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
