Abstract: Considering the particularity of pneumatic system, a new modeling method based on pneumatic dual-channel pseudo-bond graph is put forward. According to this method, a completed bond graph model of pneumatic driving system is presented. A CAD software, PneuCAD, which has five main functions including pneumatic circuit drawing, design for pneumatic power circuit, design for pneumatic control circuit, simulation and model selection, is also developed.
