The Quantification Research of Engine Body Defect that Tested by Ultrasonic Phased Array

Abstract:

After a long run, the places of body cooperate with valve very easy to produce fatigue cracks. This cracks if not detected, extremely easy to have the accident. As the most commonly used testing equipment, ultrasonic nondestructive testing is often used to detect the engine body. However, most of the existing ultrasonic nondestructive testing equipment is used to detect whether there is a defect, there is little research the specific size of defects. According to the principle of ultrasonic emission, theoretical calculation and combined with test block, get the body phased array detection method.
