Simulator for training and certification of specialists in ultrasonic testing PRODUCTS

摘要

1. The simulator for training and certification of specialists in ultrasonic testing of products containing product model with a controlled section with working and back surfaces, and a receiver connected in series and electrically normalizer pulse channels, each of which comprises an adjustable via Timing Elements delay line inputs connected to normalizer output pulses, the pulse generator with the amplitude controller and piezoelectric transducer mounted on a rear surface of the model, and all pezopreob azovateli differently oriented on the rear surface of the model, characterized in that it is provided with a multivibrator having an input connected to the output pulses of the normalizer, each of the electrical channel is provided with a controllable on-off switch connected between the piezoelectric transducer and the pulse generator with the amplitude controller, the second output of which is connected to the receiver input and control input - to the output of the multivibrator, and the piezoelectric transducers are made coincident.; 2. The simulator of claim 1, characterized in that each of the electrical channel is provided with three discrete switches Timing elements adjustable delay line to simulate the time proportional to the propagation time of ultrasonic waves to the simulated defect and inversely proportional to the velocity of ultrasonic vibrations in the material of the test object, angle input of the ultrasonic beam and the distance from the piezoelectric transducer to the controlled section.; 3. The simulator of claim 1 or 2, characterized in that each of the electrical channel is provided with a multiposition switch, whose input is connected to the first output of the switch-off of the same channel, and outputs - with piezoelectric transducers, respectively, placed at different distances from the controlled sections of the model, and three discrete switch Timing delay line elements are synchronized with a multiposition switch.
