Modeling and Simulation of Fluid Power Systems using Easy5
This course has been designed to give the hydraulics engineer a basic understanding of the issues and difficulties surrounding modeling and simulation of fluid power systems. It is geared towards the user who already has a general understanding of the Easy5 modeling, simulation and analysis environment as well as knowledge in the area of hydraulics design.
Students will learn about the specific issues that arise when building and analyzing a fluid power model. They will gain hands-on experience by building a number of different systems using predefined hydraulics and valve kit components as well as incorporating general purpose components and user-defined Fortran code. Models will include components such as valves including valve dynamics, pumps, circuits with multiple loops and heat exchangers. Open and closed loop systems will be built.
The course will cover the importance of calculating steady state conditions and provide tips and insights into how to do this. Simulation and transient water hammer effects will be discussed as well. Students will learn how to include temperature considerations in their models and how to use Easy5 components to parameterize their models.
