- Abstract:
- Electro-hydraulic servo valve widely used in servo system is one key component translated electronic signal to hydraulic signal. The servo valve capability influences the character of servo system directly. Flow characteristic is one important performance index judging servo valve capability. To master their characteristic, must do many experiments. Virtual instrument technology is adopted in one testing system of Servo Valve Flow Characteristic; soft measure method can test steady-state flow and instantaneous dynamic flow; all test data can be on-line processing, storage and printed. According to testing result, the valve flow characteristic can be calculated automatically. Rationality and reliability of this testing system is verified by practical test and contrast experiment.
