Course detail

Vibration and Noise Powertrain

FSI-9VNP Acad. year: 2022/2023 Winter semester

The course introduces the theoretical foundations of analytical and numerical methods of noise, vibration and harshness with subsequent application of these methods to selected problems of powertrains of motor vehicles. Emphasis is placed on the physical basis of a description of selected processes and their solution by means of computational models. The methods are presented using selected examples from engineering practice.

Learning outcomes of the course unit

The student will acquire the ability to critically evaluate powertrain vibration and noise and apply analytical and numerical methods. The student will apply these skills to the research of vibroacoustic systems and the need to analyse the processes occurring in powertrains.

Prerequisites

Knowledge of mathematics taught at the bachelor’s degree level and necessarily includes linear algebra (matrices, determinants, systems of linear equations), differential and integral calculus and ordinary differential equations.

Knowledge of basic kinematics, dynamics and strength of materials.

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 final assessment verifies the theoretical knowledge acquired in lectures and during independent study in the form of a research study or critical review on the problems of vibrations of elastic bodies or sound propagation in acoustic space.

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 simulations.

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.
