Abstract:
To decrease the pressure impact of hydraulic system, H type filter is presented. Its principle and filter theory is depicted in detail. Based on the motion derivation equation and liquid continuous equation, the dynamic model of the filter is formulated. The affection of the internal parameters of the filter on the filter performance is analyzed by the simulations and experiments. The accordance of the simulated and experimental results show that the system impendence is local minimum at the resonant frequency with the application of H type filter for the hydraulic system. The impendence is low in the medium and low frequency region, which is obviously lower than the resonant frequency. So it is possible to design a small volume filter to satisfy the filter performance. When the radius and length of the filter bottleneck is moderate, the more the volume is, the fewer the impendence and the better the filter performance. 12 figs, 11 refs.
