Electro Hydraulic Systems

Aim

The course aims to give an in-depth knowledge in the interaction between hydraulics, electromechanics and electronics, as well as how computer tools can be used for the analysis and development of complex mechatronic systems.

After the course each student should:

• understand the relations between motion, force, magnetic flow density and electric current in an electromechanical design inducing its limits.
• be able to handle, evaluate and analyze simulation results from mathematical models of mechatronic systems.
• be able to create state machines for implementing control or/and reference signals for control systems.
• be able to create models of physical systems using equation-based modelling languages.
• be able to use co-simulation for analysis of mechatronic systems.
• be able to individually present a mechatronic design process through both digital media and written report.

Content

The course makes primarily use of simulation technology for understanding the phenomena, opposing requirements and challenges that exist within electro-hydraulic systems. Simulation technology is the main method for evaluation of different technical solutions throughout the course, where the student will be challenged with several different problems typical for modern machine design. Example of that include tolerances in parameters, gap, friction, bi-stable systems, stiffens variations in actuators and signal delays in digital systems. Load balancing in multi-axis systems with only one power source is an example of how energy efficiency is studied. Based on earlier courses in mechatronics the knowledge about sensors is further extended about measuring mechanical quantities. A major part of the course focus on integrated analysis of system solutions. Lectures follows the information propagation through mechatronic systems, from sensor to actuator.
