Course detail

Vibration and Noise of Vehicles

FSI-QDZAcad. year: 2019/2020

The subject should serve as an introduction of the most important problems of noise, vibration and harshness applied on motored vehicles. Current computational and experimental methods used in the development of motor vehicles are presented to the students. The emphasis is laid upon the mathematical and physical foundations of calculation models and the respective software as well as the verification of results of the computer modelling by way of appropriate experimental methods. Selected examples of application of the subject matter in technical practice are also presented.

Learning outcomes of the course unit

The course gives students the opportunity to learn about current computational models, applied at motor vehicle development. Students will gain the knowledge about the up-date numerical methods applied for a solution of noise and vibration problems.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

The course-unit credit is conditioned by active participation in the seminars, proper preparation of the semester work and fulfilment of the conditions of the control tests. The exam verifies the knowledge gained during lectures and seminars and is divided into a written theoretical part, part of the computational solution of vibrations and noise and oral part. The exam considers the work of the student in the exercise. The student has to score more than one half of points for the successful completion of the test.

Language of instruction


Work placements

The objective of the course is to make students familiar with state-of-the-art of noise and vibration and enable the solution of various problems of motor vehicles by computational and experimentational methods.

Specification of controlled education, way of implementation and compensation for absences

The form of replacement of missed lessons is solved individually with the guarantee person of the subject.
