Original Kurzfassung:
Transmission lines are the most simple elements in a fluid power system from the point of view of traditional fluid power system design, simply connecting two individual ports of different components without introducing any additional dynamic effects. In reality, this wishful thinking works only when the system operates quasi-statically with respect to the time constants of wave propagation across the lines. An increasing number of industrial applications faces problems by pushing fluid power systems to operating frequencies high enough to excite significant dynamic effects in transmission lines. In order to mitigate these problems in a model-based systems engineering framework, efficient computational methods for the modelling and simulation of hydraulic transmission lines are crucial. This paper gives an overview of the state of the art in computationally efficient simulation models with a special emphasis on very compact low order models.
