Pressure pipeline ultrasonic numerical simulation system based on cylindrical coordinate system

The invention discloses a pressure pipeline ultrasonic numerical simulation system based on a cylindrical coordinate system, and aims to solve the problems that in the pressure pipeline ultrasonic field simulation process, the cylindrical space of a pipeline is difficult to accurately describe through rectangular coordinates, and the actual ultrasonic detection imaging precision of the pressure pipeline is low. According to the ultrasonic simulation system and method for the three-dimensional typical defects of the pressure pipeline, ultrasonic simulation under a cylindrical coordinate system is applied to detection of the pressure pipeline, the accuracy of ultrasonic detection of the typical defects of the pressure pipeline is improved, meanwhile, technical and theoretical bases are provided for actual ultrasonic detection work by optimizing the design of an observation system, and the practical application prospect is wide. And establishing an interpretation process system of the pressure pipeline ultrasoni
