Actuality of theme

Increasing the requirements for the quality of products, increasing the productivity of the main technological operations, the need to increase the informativity, reliability and obtaining an objective document of control have necessitated the automation and visualization of non-destructive testing. With manual control of preparatory operations, control, evaluation of defective areas, decoding of results, their registration and issuance of a conclusion is carried out by the operator. The quality of these operations depends largely on his qualifications, psycho-physiological state, integrity and environment. The greater the number of control operations will be mechanized and automated, the more objective data can be obtained about the quality of the product.

The urgency of this topic is that automation of production simplifies the control process, and also can replace some processes of production. Known foreign work-manipulators have a significant drawback - a high price, and in our country work manipulators of the same type or the same type are not manufactured. Because of this, the automation of domestic production and further control of manufactured products is high value, and not every manufacturer or company can afford to use a robot-manipulator. Therefore, it is proposed to create a robot-manipulator model for the training of specialists who in the future will program such robot manipulators for work. Due to the high price of industrial robot manipulators, their availability in higher education institutions is impossible, therefore, it is proposed to print a design of this similar model using a 3D printer and using as a source of propulsion power and stepper motors.

The dissertation deals with the issues of control of heat exchangers of steam generators in nuclear power plants. The internal diameter of the heat exchanger tubes is only 16 mm, which necessitates the miniaturization of the sensor and access to the testing object only from inside of tube. The functional scheme and algorithm of work according to system requirements are proposed. The novelty of the work is combining the amplitude and phase methods of signal processing from the eddy current sensor in order to increase the probability of detecting defect signals. Also, the project proposed a sensor for control presented a harvesting drawing. Appropriate simulations have been carried out to confirm the relevance of the proposed processing method, in particular to improve the accuracy of the method using phase processing, which suggests the use of R-statistics.
