Abstract

Discrete fluid power technology attracts great attention because it enables energy efficiency and robust system architectures. However, the discrete nature of this technology naturally brings shifting phenomenons into the picture. For fluid power system the relative high inductance of fluid transmission lines often impose pressure oscillation/ pressure waves to occur in systems operated discrete or very fast. The current work focus on developing an analytical algorithm computing the flow requirement into a cylinder chamber through a transmission line that will impose a smooth pressure change in the cylinder chamber. This is realised based on a lumped parameter transmission line model. The algorithm is tested with two different transmission line models.
