Transient phenomena in pneumatic transmission lines. I - Model comparison on the basis of step response of semi-infinite lines. II - Step response of throat-terminated transmission lines. III - Dynamics of volume-terminated transmission lines
Abstract
Transient phenomena in various pneumatic transmission lines are theoretically studied. Both qualitative and quantitative points are made on the basis of immitance function models of the transmission line system. Analytical and numerical step responses of semiinfinite, throat-terminated, volume-terminated, and branched line systems are obtained in order to compare the line models, predict the reflection waveform and wave distortion, and evaluate the nonreflection matching technique. The analytical and numerical results are evaluated by experimental responses to positive and negative step inputs.
