| Abstract: | Pneumatic-hydraulic devices of controlling edge position find wide use in textile,printing,packing manufacture,etc.The properties of pneumatic sen- sor dominate the performance of the device.The paper presents that on the basis of the developed flow model in pneumatic sensor,orthogonal test and variance analysis are applied to the selection of the structure paramaters of pneumatic sensor.Proof tests are made in the device with optimizing structure parameters.These results indicate that the pressure variation in the diaphragm chamber of pneumatic-hydraulic servo-valve is obviously affected by magni- tude of fixed orifice in the pneumatic system and structure size of main jet in the sensor.Because of optimizing structure paramaters of pneumatic sensor the dynamic characteristic of the device is improved. |
