I will right click and drag to create a hydraulic branch, and then type in relief valve to get the component. We will use a pressure relief valve to do that. We need to limit the pressure coming from the pump. I will connect the P port of our valve to the high side of the pump. I will increase the size of this valve to make it commensurate with the pump, and leave the rest of the settings as they are. There are multiple parameterization options, so I can select the one appropriate for the datasheet that I have, or I can use one that's appropriate for measured data.

I'll type in 4, and select from one of the directional valves that are available.ĭouble clicking on the block, I can go in and specify the different parameters. To control the flow of fluid from the pump to the hydraulic actuator, we need a directional valve. I click and drag to create an ideal hydraulic connection, type in reference, and here I have an ideal hydraulic reference, which will represent our tank. We will use a hydraulic reference to represent that. Our pump needs to draw fluid from a tank. I can specify the pump displacement here. Here I can see a list of the pumps I can choose from, and I will select a fixed displacement pump. I will click on the diagram, and type in the word pump. The first thing that we'll need to add into our system is a pump. This will open up a Simulink model with the settings recommended for Simscape models. To start, we will enter the command ssc_new into the MATLAB ® command window. I'll now switch over to the model so you can see how this is done. We will then connect this to a realistic model of a three-dimensional mechanical system to see how it behaves. The model we build will look like this, and we'll see when we run our simulation that the piston goes over its entire range of travel. We will model this system within the Simulink ® environment using Simscape Fluids. A motor will drive the shaft of the pump controlling the speed, and a control system will adjust the position of the valve. In our model of the hydraulic actuation system, the spool inside this valve controls the flow of pressure from a pump to either side of a hydraulic cylinder, which can extend and contract.

In this demonstration, we're going to see how to model a hydraulic actuation system using Simscape Fluids.
