Dynamics of Power Machines and Their Accessories (FSI-LDS)

Academic year 2018/2019
Supervisor: doc. Ing. Vladimír Habán, Ph.D.  
Supervising institute: EÚ all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The aim is deepening interaction of mechanical, hydrodynamic, thermal and electrical systems.
Learning outcomes and competences:
The diagnose and tuning ability of the dynamic system in energetic services with respect to noise and vibrations.
Prerequisites:
Basics in hydrodynamics, thermo mechanics and the body dynamics
Course contents:
The goal of this subject is to show the students examples of the interaction of systems of diferent physical naturel 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.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes:
Credit and Examination (oral exam)
Controlled participation in lessons:
Seminars and written tasks on the excercises
Type of course unit:
    Lecture  13 × 3 hrs. optionally
