The design of hydraulic transmission lines for control and actuation requires accurate knowledge of their dynamic response: some standard techniques are known to obtain a consistent dynamic model of a fluid line, including the contribution of inertia, compressibility and friction. In this paper an efficient procedure is developed for simulating the dynamic response in both the frequency and time domains, focusing the attention on the modal analysis of a discretized model of a fluid line. A bi-dimensional approach is adopted, modeling the laminar flow frequency-dependent friction by means of non-integer order differential laws, which may improve the accuracy of the simulated responses in comparison with more traditional Newtonian models.

Abstract

The design of hydraulic transmission lines for control and actuation requires accurate knowledge of their dynamic response: some standard techniques are known to obtain a consistent dynamic model of a fluid line, including the contribution of inertia, compressibility and friction. In this paper an efficient procedure is developed for simulating the dynamic response in both the frequency and time domains, focusing the attention on the modal analysis of a discretized model of a fluid line. A bi-dimensional approach is adopted, modeling the laminar flow frequency-dependent friction by means of non-integer order differential laws, which may improve the accuracy of the simulated responses in comparison with more traditional Newtonian models.
