- W4280492271 abstract "In this thesis, the concept of hydraulic pulsating filter is explored and developed. The filter or resonator is designed to attenuate the pulsation that occurs when the hydraulic pump is discharged. Pumps pulsate over a range of frequencies, depending on pump design, speed, displacement, and other factors. The objectives of this work are to create a conceptual design and mathematical model of the pulsation filter concept, to conduct simulations and analyses to determine the feasibility of the concept, and to compare alternative designs for achieving the goal of attenuating pulsation at low frequencies (up to 100 Hz). These concepts include using standard components, as well as consideration of modeling alternatives. In order to solve the feasibility problem, the lumped parameter method is used for analysis, and key concepts are verified by experiments. This study started from the theoretical review of Helmholtz resonator and branch hose. After the theoretical review, experiments were presented to verify these concepts. On this basis, a novel pulsation attenuation scheme Super Volume is modeled and developed. Experiments were also presented to evaluate the Super Volume concept. The experimental results show that Super Volume is a feasible way to attenuate low-frequency fluid pulsation by manipulate device parameters. This work contributed to the development of passive low-frequency hydraulic fluid power pulsation solutions." @default.
