一种斜探头超声场声压分布的测量试块
摘要：
本实用新型涉及一种适用于斜探头超声波检测时测量超声场声压分布的试块，其为长方体，内部设置有一个1/4圆弧形的通孔，底部一端加工有一个由连续的半圆形凹槽构成的反射体；其中通孔用于检测斜探头超声场横向声压分布；其中由连续的半圆形凹槽构成的反射体用于检测超声场声束纵向声压分布。通过本实用新型的试块检测探头的超声场声压分布，可以准确的判断超声场的结构，增加无损检测的精确度。
摘要（英）：

The utility model relates to a test block for measuring the sound pressure distribution of an ultrasonic field when an angle probe is used for testing ultrasonic waves. The test block is in the shape of a rectangular solid. A one-fourth-circular arc through hole is formed in the test block; a reflecting body formed by continuous semi-circle grooves is machined at one end of the bottom of the test block; the through hole is used for detecting the transverse sound pressure distribution of the ultrasonic field of the angle probe; the reflecting body formed by the continuous semi-circle grooves is used for detecting the longitudinal sound pressure distribution of sound beams of the ultrasonic field. The test block is used for detecting the sound pressure distribution of the ultrasonic field of the angle probe, so that the structure of the ultrasonic field can be accurately judged, and the accuracy of nondestructive testing is improved.
