Ultrasonic Rail Flaw Detector Research And Development

With the development of electronic technology and ultrasonic technology, Ultrasonic inspection technique has become one of the major means in flaw detection. The paper designs a equipment that using the ultrasonic wave to detect rail's flaw. It is a supplement to high-speed ultrasonic detector. It plays significant roles in guaranteeing the railroad normal operation. The paper mainly completed the following works:1) The design of the flaw detective car,Finished the flaw detective car by using the modern CAD technology, and also apply virtual assembly technology in this design, especially use ADMSA to analyzing the key part of the flaw detective car. All these technology have greatly shorted the time of the design and reduced the cost of the design, and improved the quality and efficiency of the design.2) The design of control systemThe paper design a microprocessor control system that using AT89C52 as its core. It gives the detection pulse as well as data collection pulse. Considered the requirement of some personalization, it can show the whole distance the car traveled and give a alarm when the flaw detective car lacks of water.At the end of this paper give a summarize of this design and outlook of ultrasonic flaw detection technology.
