Longitudinal and transverse wave integrated ultrasonic probe as well as testing system and method of elastic modulus and distribution

Abstract

The invention discloses a longitudinal and transverse wave integrated ultrasonic probe as well as a testing system and method of elastic modulus and distribution. The longitudinal and transverse wave integrated ultrasonic probe is designed and carried by a manual C imaging scanner, position information feedback in directions of X and Y axes in free sliding motion is acquired, and elastic modulus and distribution quantitative characterization is realized with an imaging technique. Elastic modulus and distribution of a heterogeneous anisotropic material is acquired quickly and accurately with the testing method of elastic modulus and distribution of the longitudinal and transverse wave integrated ultrasonic probe in combination of an ultrasonic automatic scanning technique, a virtual instrument technique, an ultrasonic signal analysis and processing technique, a digital imaging technique and other techniques, and the testing method is suitable for testing elastic modulus and distribution of heterogeneous anisotropic plate type composite.

Description

technical field [0001] The invention relates to a kind of non-destructive testing, in particular to a longitudinal and transverse wave integrated ultrasonic probe, elastic modulus and distribution testing system and testing method. Background technique [0002] Non-destructive testing (NDT) is an important means to ensure product quality and performance and stabilize production processes in the modern industrial field. Its technical level can reflect the industrial technical level of the sector, the industry, the region and even the country. [0003] Ultrasonic testing technology UT has always been a hot spot in nondestructive testing research. In foreign nondestructive testing literature, the proportion of ultrasonic testing content accounts for about 45%. Ultrasonic testing technology is also the most used one among the five conventional nondestructive testing technologies. Compared with other conventional non-destructive testing technologies, it has the characteristics o...
