Latest Patents

Yongna Shen holds a patent for a "Magnetoacoustic emission detection method for fatigue damage of ferromagnetic metal component." This method involves generating an excitation magnetic field using a sine wave voltage signal, gradually increasing the loading voltage until a magnetoacoustic emission signal with a bimodal envelope is acquired. The process includes taking a corresponding voltage peak value as a reference voltage and generating an excitation magnetic field using a square wave voltage signal. The method allows for the calculation of the average value of peak-to-peak values of the magnetoacoustic emission signal, which serves as a characteristic parameter. This parameter changes with the development of fatigue cracks, providing timely early warnings for potential component failures.
