Description
Technical field
The present invention relates to the Ultrasonic NDT field, relate in particular to the apparatus and method of carrying out Ultrasonic NDT for the inner beam corner region of many beams co-curing enclosed construction.
Background technology
Ultrasonic non-destructive inspection techniques is one of Main Means of NDT of composite, and is through development for many years, very ripe.Its principle is that the acoustic characteristic of material and the variation of interior tissue produce certain impact to hyperacoustic propagation, by detection Knowing material performance and the structural change to ultrasound wave degree of susceptibility and situation when utilizing ultrasound wave to propagate in detected material.When ultrasound wave enters object and runs into defective, part sound wave can produce reflection, receiver is by analyzing reflection wave, measure the thickness of material, and find hiding inherent vice, perhaps analyze properties of materials such as metal, plastics, compound substance, pottery, rubber and glass etc.Ultrasonic detecting technology commonly used can be divided into pulse echo method, water spray through transmission technique.Automatic detection system for large-sized structural parts mostly adopts this two kinds of technology.These two kinds of technology respectively have relative merits: pulse echo method can access more defect characteristic information, but the profile tracking accuracy is had relatively high expectations; The water spray through transmission technique requires lower to the profile tracking accuracy, better to the detection effect of sandwich construction and large thickness structure.
Along with compound substance gradually substituted metal become the primary structure material of aircraft, the size of composite product is increasing, its structure also becomes increasingly complex, and therefore utilizes large-scale Ultrasonic C-Scan checkout equipment to be difficult to reach 100% Non-Destructive Testing to product.For instance, the overhanging box section of Boeing 787 horizontal tails has adopted advanced many beams co-curing technology, its design feature is large (approximately 14 meters of maximum lengths), integrally closed structure of size, this structure has been brought huge challenge to Non-Destructive Testing, use conventional large-scale Ultrasonic C-Scan equipment, probe is difficult to arrive the corner region of inner regional, especially inner beam of product.Therefore must take the manual detection device auxiliary detection, and the servicing unit that manually detects final detection effect and reliability have been determined.No matter common ultrasonic detection equipment manually detects or conventional automatic detection system, all probe can't be stretched into enclosed construction inside, thereby helpless for the detection of enclosed construction inner beam corner regions.If have specially automated machine scanning system made to order for enclosed construction, then need to spend high expense, and often can only detect the close structure of physical dimension, extensibility is relatively poor.
Summary of the invention
