The excitation source of non-destructive testing determines the ability to detect defects and the clarity of defect imaging. Finite element numerical simulation is an effective way to analyze the relationship between electromagnetic fields and defects. Aiming at the problem that there is no MAX038 simulation library for many simulation platforms, this article first studies the internal structure and working principle of MAX038, and realizes the creation of the MAX038 simulation library. Then use the packaged MAX038 library to design a signal generator based on MSP430 and MAX038, optimize the detection algorithm of the simulation library, realize the automatic generation of test results of the parameters to be tested, and improve the accuracy and efficiency of the simulation library verification. Finally, the simulation program is transplanted to the actual hardware circuit. The experimental test results show that the function, accuracy and stability of the established MAX038 simulation library match the hardware chip, meet the design requirements of the simulation library, and have good practicality in non-destructive testing. value.
