Course detail

Dynamics of Power Machines and Their Accessories

FSI-LDSAcad. year: 2020/2021

The goal of this subject is to show to the students examples of the interaction of systems of diferent physical nature and their dynamic behaviour. Above all, the physical basis and modelling of system elements in real operating conditions will be discussed. Based on the system modelling, the diagnostic fundamentals and tuning of coupled systems of energetic machinery will be explained.

Learning outcomes of the course unit

The diagnose and tuning ability of the dynamic system in energetic services with respect to noise and vibrations.

Prerequisites

Basics of hydrodynamics, thermomechanics and the body dynamics.
