Resonance and Transient Response of Pressurized Complex Pipe Systems

抄録

Resonance in pressure conduits is studied on complex pipe systems which are composed of series, branching and parallel piping lines. In such complex systems, shapes of the resonance curves and also resonance frequencies differ remarkably depending on the location of input or output of the lines. It is shown that these phenomena are generally observed in a simple line or in a system with many degrees of freedom. Next, transient response plots are obtained experimentally for conduits lines with various boundary conditions such as open-end, closed-end and some loads. These plots are compared with results of numerical analysis obtained by the characteristic method. Their agreement is good.
