1, ultrasound diagnosis
The vast majority of people before birth has been with it "dealt with" - in order to understand our health status, our mother in a few months when we are still the fetus to take us to the B ultrasound. Ultrasound is one of the most widespread and influential applications of ultrasound technology in clinical medicine.
2, ultrasound ranging
If the ultrasound is the most popular ultrasound applications, the most popular ultrasound technology is ultrasound ranging. The most common of these is the reverse assist system (commonly known as "reverse radar"). The system sends out ultrasonic waves, uses the ultrasonic reflection back to measure the distance, and reminds the driver of the surrounding obstacles through voice prompts to guide the safe reversing of the car.
Because the calculation is convenient and rapid, and the measurement accuracy can meet the requirements of industrial utility, so with the development of manufacturing upgrades and artificial intelligence, in recent years, ultrasonic ranging has been widely used in mobile robots.
3, ultrasonic underwater communication
At present, ultrasonic underwater communication is the most widely used and important device is sonar. The highest is the navy with its submarines and other underwater objects for detection, localization and tracking, but also widely used, sonar technology is also widely used in torpedo guidance, fish detection, marine oil exploration.
3, ultrasonic processing
The application of ultrasonic technology in the industrial field is mainly ultrasonic processing. Ultrasonic processing is the use of ultrasound high-frequency vibration, micro-impact on the material, so that the material processing surface gradually broken special processing.
4, ultrasonic welding
Ultrasonic welding is the use of high-frequency vibration waves transmitted to the surface of the two objects to be welded, the surface friction between the pressurized case and the formation of fusion between the molecular layers. Mainly used in the field of plastics and metals, in the automotive, refrigeration, solar energy, batteries, electronics and other industries have a wide range of applications. Such as lithium battery pole ear welding, refrigerator and air conditioning industry, copper tube sealing.
5, ultrasonic cleaning
Good results, fast speed, no need for manual contact with the cleaning fluid, no damage to the surface of the object, ultrasonic cleaning of these advantages from where it comes from - ultrasonic cleaning based on cavitation, that is, in the cleaning fluid countless bubbles quickly formed and quickly imploded, the resulting impact will be submerged in the cleaning fluid on the internal and external surfaces of the object In the cleaning fluid in the object inside and outside the surface of the dirt stripped down, so as to achieve the purpose of precision cleaning.
6, ultrasonic flaw detection
Aerospace, railroad transportation, water conservancy projects and other major equipment and facilities, can not tolerate a little defects, that in the daily safety inspections, how to quickly and conveniently, accurately and non-destructively on the inside of the workpiece to carry out a variety of defects in the detection, location, assessment and diagnosis? Ultrasonic flaw detection is the pair of "eyes of fire".
7, ultrasonic fingerprint recognition
Wet hands can not unlock the phone, then there is no fear of water fingerprint unlock? --The answer is ultrasonic fingerprint recognition. Xiaomi 5S, Huawei Honor 10 uses ultrasonic fingerprint recognition to unlock. From the time point of view, ultrasonic fingerprint recognition should be counted as the most trendy application of ultrasonic technology.
Expanded Information
Characteristics of ultrasonic waves
1) Ultrasonic waves in the propagation of the short wavelength, the direction of the strong, the energy is easy to concentrate.
2) ultrasonic waves can be propagated in a variety of different media, and can be propagated far enough distance.
3) ultrasound and sound transmission medium interaction is moderate, easy to carry information about the state of the sound transmission medium diagnosis or sound transmission medium to produce the effect and treatment.
4) ultrasonic waves can be effectively propagated in gases, liquids, solids, solid melts and other media.
5) Ultrasonic waves can transmit energy.
6) Ultrasonic waves produce reflection, interference, superposition and *** vibration phenomena.
