Abstract:

The amplitude frequency response transfer gain curve of 0.170 inch I.D. blocked pneumatic lines of the type used in flueric systems was experimentally determined. The ecectric-pneumatic analogy was used, in conjunction with a gain envelope technique, to develop theoretical predictions of the gain curves of blocked pneumatic lines by several theories. Correlation with experiment showed that any theory using a constant pneumatic resistance would be in error when the signal frequency was greater than a characteristic frequency of the line. A high-frequency theory, based on the work of Nichols The linear properties of pneumatic transmission lines, Transactions of the American Society of Mechanical Engineers, no. 2, 79583-874 1957, was developed and, at least, predicted the resonant gains within 2 db and the resonant frequencies within 10 per cent for all signal sizes. A rapid nomographic solution for the gain curve, based on this high-frequency theory, is included. Author
