[0002] As my country's railway mileage continues to grow, railway transportation speed continues to accelerate, and urban rail transit becomes more and more developed, the requirements for engineering machinery and equipment to ensure the safety of railways and urban rail transit are also getting higher and higher. Rail inspection equipment based on the principle of ultrasonic flaw detection has been widely used in railway engineering systems and urban rail transit. Rail inspection equipment based on the principle of ultrasonic flaw detection must use coupling fluid as a medium to transmit ultrasonic waves to the inside of the rails for damage detection. Wheel-type ultrasonic flaw detection technology has developed rapidly in the field of rail flaw detection due to its fast detection speed and good adaptability to the rail surface. The current wheel-type rail flaw detection vehicle has a maximum detection speed of 80km / h. As a key link in the use of ultrasonic probe wheels, the performance of the probe needs to be calibrated before using the ultrasonic probe wheel to ensure the accuracy of the ultrasonic detection operation.
