Description
Technical Field
The utility model relates to a nondestructive test device field specifically is a combined material's for aviation self-focusing ultrasonic phased array detection device.
Background
The nondestructive detection is to detect whether the detected object has defects or non-uniformity by using the characteristics of the substance such as sound, light, magnetism and electricity without damaging or affecting the use performance of the detected object, and give information such as the size, position, property and quantity of the defects. Compared with destructive detection, nondestructive detection has the following characteristics.
The first is non-destructive, because it will not damage the use performance of the detected object when detecting; secondly, the detection is comprehensive, and as the detection is nondestructive, 100% of the comprehensive detection can be carried out on the detected object if necessary, which cannot be achieved by destructive detection; and thirdly, the method is omnirange, and the destructive detection is generally only suitable for detecting raw materials, such as stretching, compression, bending and the like commonly adopted in mechanical engineering, and the destructive detection is performed on the raw materials for manufacturing.
For finished products and in-service supplies, destructive detection cannot be carried out unless the products and the in-service supplies are not ready to be continuously used, and nondestructive detection does not damage the service performance of the detected objects. Therefore, the method not only can carry out the whole-process detection on the raw materials for manufacturing, all the intermediate process links and the final finished products, but also can carry out the detection on the equipment in service.
When a conventional linear array phased array probe detects composite materials for aviation, such as CFPR carbon fiber composite material plates, the quantitative accuracy of the length of a defect after the defect is found is related to the width of a linear array probe wafer used by the probe, and the wider the width is, the poorer the quantitative accuracy in the length direction of the defect is; the narrower the width, the higher the quantitative accuracy in the length direction of the defect, but the smaller the width, the less the ultrasonic energy, because the composite material itself still has certain sound attenuation characteristics, the low energy ultrasonic wave can not penetrate the whole plate, so that the detection can not be carried out by using a wafer with very small width.
