Course detail

Vibration and Noise Powertrain

FSI-9VNPAcad. year: 2020/2021

The subject should serve as an introduction of the theoretical problems of noise, vibration and harshness applied on powertrains. The emphasis is laid upon the mathematical and physical foundations of calculation models. 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 critically evaluate the vibrations and noise of powertrains and the application of analytical and numerical methods. These skills will be used by the student in a development of new methods capable of analysing complex events occurring in powertrains.

Prerequisites

Matrix calculus, differential and integral calculus, differential equations. Kinematics, Dynamics and Strength of Materials. Fourier analysis and Fourier transformation.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline.

Assesment methods and criteria linked to learning outcomes

The exam verifies mainly the theoretical knowledge gained during the lectures and the independent study and includes the elaboration of a task on the issue of vibration of elastic bodies and the problem of sound propagation in the acoustic domain.
