Vibration and Noise Powertrain (FSI-9VNP)

Academic year 2020/2021
Supervisor: prof. Ing. Pavel Novotný, Ph.D.  
Supervising institute: ÚADI all courses guaranted by this institute
Teaching language: Czech or English
Aims of the course unit:
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.
Learning outcomes and competences:
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.
Course contents:
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.
Teaching methods and criteria:
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.
Controlled participation in lessons:
Teaching takes place in the form of expert consultations and debates on the problem at pre-defined dates.
Type of course unit:
    Lecture  10 × 2 hrs. optionally                  
Course curriculum:
    Lecture Vibrations of nonlinear systems.
Applications of multibody dynamics on solution to flexible body dynamics.
Bearings and special vibration problems.
Description of sound sources and sound propagation through acoustic domain.
Acoustic analogies.
Internal combustion engine noise and vibrations.
