Learning Outcomes

Modelling and simulation of hydraulic system including hydraulic valves, hydraulic cylinder and load mass using Matlab/Simulink.


Content Core content Complementary knowledge Specialist knowledge
1. Modelling and simulation (Matlab/Simulink) as a tool.      
2. Basic modelling techniques of hydraulic systems.      
3. Properties of the hydraulic fluids. Modelling a state equation of the fluid.Calculation of the effective bulk modulus.     
4. Modelling of an orifice.  Orifices in series/parallel.  Saturation of the orifice by the cavitation. 
5. Four way valve (non-linear) modelling. Dynamics, flow paths, control.  Spool valve leakage modelling.   
6. Hydraulic cylinder modelling together with a simple mechanical model.   Collision model of the cylinder ends.   
7. Dynamic friction model.     
8. Modelling of hydraulic pumps and motors.     
9. Interaction between of models of different sub-components; complete hydraulic system modelling.
