PUB – Eindimensionales Modell eines hydropneumatischen Speicher basierend auf der finiten Volumenmethode
Im Rahmen der IFK 2020 in Dresden ist eine Veröffentlichung zum Thema „Pneumatik-Simulation“ erschienen.
The goal of this paper is to develop and to analyse a time efficient simulation approach for the gaseous phase within a piston accumulator depending on the accumulator’s load cycle. Temperature, pressure, density and velocity profiles inside of the gaseous phase are calculated transiently in order to achieve that goal. The simulation model is derived in one dimensional environment to save computational effort. Having derived a valid model of the gaseous phase it will be possible in future works to replace the expensive position measurement system by pressure and temperature transducers and then use the model to calculate the position of the piston and therefore estimate the state of change.
