用于碳纖維復(fù)合材料的高頻電磁渦流檢測系統(tǒng)集成
[Abstract]:With the increasing application of CFRP in practical engineering, damage detection for its structure becomes more and more important. At present, there are many non-destructive testing methods for carbon fiber composites. Eddy current testing methods are non-contact, no coupling agent, and can be used in the process of carbon fiber production, so it has been widely paid attention to by academic and engineering circles. Carbon fiber composites exhibit a certain electrical conductivity, which makes eddy current detection possible. Because of the weak conductivity of carbon fiber composites, it is necessary to improve the detection frequency in order to obtain higher detection sensitivity. In this paper, a high frequency electromagnetic eddy current testing system is integrated to detect the common damage of carbon fiber composites. The upper computer realizes two-dimensional plane scanning by controlling the arm clamping probe, and controls the hardware circuit to realize signal generation, processing, transmission and so on. The operating frequency of the system can reach 10 MHz and the frequency can be adjusted. The main works of this paper are as follows: (1) the improvement of the hardware circuit automatic balance module is completed, and the protocol instruction format of communication with the host computer is established; (2) the communication format between the upper computer and the manipulator is analyzed. The control of the manipulator is realized based on LabVIEW language. (3) the software of the detection system is designed with the LabVIEW program, which realizes the control of the hardware circuit, the motion control of the manipulator, the display and saving of the data, and so on. (4) make different types of damage test plates, including crack damage, impact damage and delamination damage, and put them in the detection system for experimental verification, for the damage forms that are not easy to observe. The feasibility and practicability of the system are verified by the experimental results.
