Abstract

Due to the wide application of composite materials it is necessary to develop unconventional quality control techniques. One of the methods that can be used for this purpose is ultrasonic tomography. In this article an application of a robotic ultrasonic system is considered. Precise positioning of the robotic scanner and path generating are defined as ones of the most important aspects. This study proposes a non-contact calibration method of a robotic ultrasonic system. Path of the scanner requires a 3D model of controlled objects which are created in accordance with the proposed algorithm. The suggested techniques are based on implementation of structured light method.

Highlights

Nowadays advanced technologies require development of high-quality materials
This study suggests an ultrasonic testing technique applying a robotic scanner
Taking into account the fact that non-contact technique is simpler, less time consuming and more convenient we propose to apply this method for effective ultrasonic testing by a robotic scanner

Summary

Introduction

Nowadays advanced technologies require development of high-quality materials. Carbon fiber composites are widely used for construction of complex shaped objects. Carbon fiber reinforced silicon carbide (SiCf/SiC) was suggested for further development of the very high temperature reactor (VHTR) due to its ability to tolerate higher operating temperature [1] This complex structure of materials causes the necessity of unconventional testing techniques. 2. General aspects of testing technique Methods of positioning of the scanner and controlled object were studied for robotic ultrasound tomography system (see Fig.). General aspects of testing technique Methods of positioning of the scanner and controlled object were studied for robotic ultrasound tomography system (see Fig.1)
