Ultrasonic Condition Monitoring Technique and Microstructure

In conventional ultrasound nondestructive condition monitoring, testers use his test experience to interpret defects while analyzing ultrasound echoes. Due to the coarse structure of the material, the ultrasonic attenuation is more, so sometimes the false impression of the defect is given and unreliable results are given. Conventional detection methods are too subjective and depend on the effectiveness of testers so reliability of detection is low. In order to overcome these restrictions, this paper proposed a correlation between multi-question ultrasonic technology, material characteristics, attenuation, sound speed and particle size.

The use of ultrasonic examination in condition monitoring is a relatively new approach in the field of condition monitoring. Monitor high-frequency sounds generated in factory machines and systems. Ultrasound can not be heard by the human ear, it occurs at a frequency of 20 kHz or more. Different ultrasonic devices record ultrasonic waves between 20 kHz and 100 kHz. There are two types of ultrasonic monitoring, aerial and structure. - Radiation is the energy that is derived from energy and propagates in the form of waves or fast particles. Radiation is emitted mainly from atoms. An atom is the smallest particle of matter. When radiation is emitted, it excites orbital electrons in the atom to vibrate the electrons, thereby releasing energy. There are two types of radiation: ionizing radiation and nonionizing radiation.

However, it is still unknown how the ultrasonic vibration input variable affects the microstructure and mechanical properties of the manufactured part. 7.3.2. - Ultrasound is an important feature of the technology used in today's world. The medical community uses ultrasound and X-rays in everyday life. Ultrasonic waves are high frequency sound waves, ultrasonic waves generate sound waves, these sound waves are injected into the body to generate echo echoes, these echoes can be recorded and the structure under the skin can be seen . There are thousands of ultrasounds that help you to see certain diseases and symptoms that doctors and patients can not see.
