The objective of this study is to develop a personal CAD system which is aimed at calculating the time response characteristics of hydraulic control systems. In the previous paper, a simulation method for fluid line systems was investigated, based upon their block diagram representations for four terminal networks. An important limitation in the method, however, was that the response could be calculated only at the up- or down-stream end of fluid lines. In the present paper, therefore, the block diagram representations of a fluid line are obtained as expanded ones for arbitary pipe positions, in order to develop the calculation method at these positions. To see the applicability of the diagram to the simulation, time responses at arbitary pipe positions are calculated under various fluid line conditions. Their results are compared with the measured responses to show the validity of the method.
