LEARNING OUTCOMES
After the course the student is able to:
- Master the fundamentals of the technological area of his/her design assignment and also
- Describe technical fundamentals of different valve and system technologies, characteristics and their typical targets of application
- Evaluate critically the applicability of different system technologies to applications representing different levels of standards
- Use catalog information to analyze the characteristics of components and to define values for parameters (static and dynamic characteristics) needed in dimensioning/system design
- Analyze component characteristics (static and dynamic) by measurement results
- Calculate the effect of components on system characteristics
- Analyze the factors which affect the energy consumption of hydraulic systems and how the energy efficiency can be enhanced by changes in system parameters and architectures
- Design and dimension an energy efficient hydraulic system that fulfills the required functions and whose technology is appropriate for the application in question and choose the appropriate components (by required static and dynamic characteristics) and fluid for the system
- Design the control needed in the operation of the system and tune a hydraulic closed loop control system
- Use firmware/software packages to design, calculate, analyze, model, and simulate hydraulic systems
- Analyze the quality of existing hydraulic systems considering functionality and energy efficiency and make well-founded suggestions for improvements
- Analyze characteristics and operation of hydraulic systems (including condition monitoring, fault and damage diagnostics, safety and environmental risks) by measurements
- Combine information from different sources (criticism of sources) and create well-defined and comprehensive system documents
