This simulation program lets you build and test hydraulic circuits to help you understand how they will perform. Its purpose is for training, rather than dynamic system design. Learn about a wide range of different systems by simply loading the circuits and operating the control valves. Training exercises are provided to help users learn about the different hydraulic components and design techniques. The program includes a number of example circuits where users can change the component sizes or settings to replicate their own equipment. Test gauges can be used to examine the performance at different parts of the circuit or readings can be taken and exported to a spreadsheet for analysis. Users can also build their own custom circuits with a simple drag and drop editor. The free version includes a limited number of circuit examples. Subscribe to access all circuits examples and create and save your own circuits. This program has been designed as a hydraulic training tool. It does not contain valve switching dynamics or fluid compressibility factors.
