Aims
The aim of this course is to develop and deepen students' knowledge in the area of machine mechanisms and hydraulic systems with a focus on sustainable development and ecology. Students will learn about biodegradable oils, their specific properties, advantages, and applications in hydraulic systems, including their role in achieving Green Deal objectives. Completing this course will equip students with the necessary knowledge to design and construct mobile working machines, emphasizing environmental impact reduction through sustainable technologies and materials.
Students will be acquire knowledge of designing and construction especially of mobile machines from the study program. They will widen and deepen their knowledge of design of regulative hydrostatic circuit, with respect to the latest development trends.
