Pneumatic Pipe Modeling: Theory and Experimental Approach—Part II

Abstract In fluid power systems, lines or pipes can have a predominant effect on dynamics. Although many studies have been carried out on hydraulic pipe modeling, there are only a few existing approaches for such problems in pneumatics. This paper proposes an experimental work in modeling of pneumatic pipes. A short state of the art situation, the nature of this problem, and different approaches of modeling pneumatic pipes are presented in Pneumatic Pipe Modeling: Theory and Experimental Approach (PART I). As the simulation of system with pipes may need an important computing time, it is crucial to use the adequate model. While it is not difficult to develop theoretical models, we need to tune them by adjusting the unknown parameters such friction factor and the thermal exchange parameter. We introduce then an experimental method to evaluate these parameters. The robustness of the models is proved through several examples and in order to validate our propositions, we compare experimental trails to the results given by the simulation.
