SYSTEM AND METHOD FOR DETERMINING STRESS OF A COMPONENT MADE OF MAGNETIZABLE MATERIAL |
摘要 |
The present system determines a significant stress value (sigma) of a component made of magnetizable material. The system has a generating stage for generating a magnetic field of varying amplitude (H); and also includes a pickup stage for acquiring a Barkhausen noise signal (MBN) alongside variations in the amplitude (H) of the magnetic field. The system is characterized by having a processing unit for calculating the reciprocal (1/MBNmax) of the maximum value (MBNmax) of the signal (MBN), alongside variations in the amplitude (H) of the magnetic field. The processing unit has a memory stage storing a linear relation between the reciprocal (1/MBNmax) of the maximum value and the significant stress value (sigma). |
