Course detail
Fluid Power Modeling
FSI-MTM Acad. year: 2018/2019 Summer semester
The cours deals with the following topics: basic theory, notions and definitions of mathematical modelling of fluid power systems and displacement pumps. It gives an overview of the main simulation tools as well as electro-hydraulic analogy. Energy transfer, efficiency and characteristics are emphasised in the part concerning the displacement pumps.
Seminars include computer simulation and examples from the research applicable in industrial practice.

Learning outcomes of the course unit
Students will be able to analyse and create a mathematical model of the fluid power system element behaviour or a model of the mechanism as a whole. They will also be able to simulate this behaviour by means of a computer.
Prerequisites
Necessary knowledge: differential and integral calculus, hydrostatics and hydrodynamics, gas mechanics, numerical mathematics, computer programming.
Planned learning activities and teaching methods
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
Course-unit credit is awarded on the following conditions – sufficient attendance and running knowledge of the subject-matter.
Examination requirements – course-unit credit, knowledge of the subject-matter and and ability to apply it to the given examples. The exam has a written and an oral part.
Aims
The aim of the course is to provide students with an ability to create mathematical and simulation models of fluid power system elements, as well as models of basic circuits of these mechanisms. Another goal is for students – to be able to predict behaviour of those systems in the design stage already.
Specification of controlled education, way of implementation and compensation for absences
Attendance at seminars is checked and possible (limited) absence may be compensated for via additional tasks.
