This circuit takes you through the different stages of a load control circuit starting from a basic system with directional valve. It explains the different problems that can occur and what can be added to solve the problem
Experiment with load control circuits
Caution!
Please note that the fluid stiffness values have been reduced in our simulation to better demonstrate the potential problems when using different load control circuits. This can be seen in delays when lifting the cylinder and oscillations when it's stopped suddenly. The issues do appear in actual systems but are only a problem apart for highly dynamic or high accuracy control systems.
Suggested exercises and observations
Step through each section of the simulation and follow the aspects identified in the course text.
