Course detail
Vibration and Noise Powertrain
FSI-9VNP Acad. year: 2021/2022 Winter semester
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.
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.
Aims
The objective of the course is to provide deep theoretical knowledge in the field of vibration and noise of powertrains and enable to solve these problems in the form of computational methods.
Specification of controlled education, way of implementation and compensation for absences
Teaching takes place in the form of expert consultations and debates on the problem at pre-defined dates.
