Abstract
Pneumatic medical and consumer devices that use compressed gas are designed using standardized components with many possible variations. A typical development project includes lengthy empirical testing to optimize component selections. Tools that can be used outside a lab to model these systems are either slow or unable to handle fluid compressibility effects at both sonic (critical) and subsonic (subcritical) flow conditions simultaneously. The modeling approach in this thesis is original because there is a lack of existing studies using bond graphs to model compressed gas medical devices in both critical and subcritical states. This research shows that using bond graphs and numerical methods is possible for a simple model to quickly approximate the dynamic response of a pneumatic system and facilitate an engineer’s ability to optimize component selection.
