Abstract
Pneumatic system is applied in a wide range of industries. There are many kinds ofpneumatic circuits that are used in different applied cases, such as transportation, clamp, press, etc. Among those pneumatic circuits, pneumatic circuit with only one cylinder controlled by one valve is primary for application, while branch circuit, which is consisted of multiple cylinders controlled by one valve, and manifold circuit, which is consisted of multiple cylinders controlled by multiple valves, is commonly applied in practices. In this paper, a simulation program for complex pneumatic circuits, especially for branch circuits and manifold circuits, is developed for model selection and characteristic calculation. Firstly, outline and specifications of the simulation program is introduced; secondly, modeling and simulation method of branch circuit and manifold circuit are explained; finally, an example of application is presented to verify the accuracy of the simulation program.
