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

Academic year 2021/2022
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 to understand to 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 of hydrodynamics, thermomechanics and the body dynamics.
Course contents:
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.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes:
Credit - attending seminars and elaboreting task.
Examination - written and oral exam.
Controlled participation in lessons:
Seminars and written tasks on the excercises.
Type of course unit:
    Lecture  13 × 3 hrs. optionally                  
    Computer-assisted exercise  13 × 2 hrs. compulsory
