Abstract
In use of pneumatic pipe lines in fluidics circuit systems for the purpose of information transmission, it is necessary to determine the suitable dimension of the pipe lines.
In this study, the dimension of the transmission pipe line giving a good matching to an information source and a load is determined from the power transmission coefficient of a fundamental transmission system composed from an information source with an internal resistance, a pipe line and a load resistance. The power transmission coefficient is expressed by a nondimensional frequency and three nondimensional parameters formed from the dimension of the pipe line and the values of the internal and load resistances. The effects of the nondimensional parameters on the power attenuation calculated from the power transmission coefficient are analytically investigated and experimentally examined.
Considering the result of these examinations, a method of design for a pneumatic transmission line is presented. It is finally explained with an example that the method of design is very practical.
