METHOD FOR ESTABLISHMENT OF CURVE ILLUSTRATIVE OF RELATIONSHIP BETWEEN INTERFACE ULTRASONIC REFLECTANCE AND PRESSURE BASED ON ROUNDED PLANAR CONTACT THEORY AND LOAD EXPERIMENTAL STATION

摘要

Provided are a method for establishment of a curve illustrative of a relationship between an interface ultrasonic reflectance and a pressure based on the rounded planar contact theory, and a load experimental station. The load experimental station comprises a pressure display device (1), a control end (2), an oscilloscope (3), an immersion ultrasonic transducer (4), a large cylindrical member (5), a small cylindrical member (6), an upper faceplate (7), a movable plate (8), a pressure sensor (9), a lower faceplate (10), an ultrasonic transceiver (11), and a small cylindrical member connection plate (12). The method for establishment of a curve illustrative of a relationship between an interface ultrasonic reflectance and a pressure based on the rounded planar contact theory and a load experimental station enable establishment of a more accurate curve illustrative of a relationship between an interface ultrasonic reflectance and a pressure and have high detection precision.
