THE APPLICATION OF DIMENSION ANALYSIS ON MAKING ABSOLUTE CALIBRATION MODEL OF TRANSDUCERS |
| |
| Abstract: | The working principle of drop hammer dynamic pressure calibration system and the meaning of absolute calibration based on this system are introduced.By means of the approximately linear model,the facts that affect the precision of absolute calibration are analyzed.According to dimension analysis,the non dimension relation equation of the factors are achieved.According to the test data,the absolute calibration model of some system whose pressure is from 200 to 600 MPa is made.The feasibility of this model is testified by means of test. |
