Due to the long-range disordered structure and randomness of magnetic moment distribution of amorphous alloys

hysteresis and magnetostrictive return lines of amorphous alloys under stress action and non-sinusoidal excitation will show multi-loop characteristics. In order to simulate this particularity

this paper proposes a simulation method of the magnetostrictive multiple loop characteristics of amorphous alloys based on microstatistics and inverse J-A model. First

the randomly distributed magnetic moments in the amorphous structure are represented by locally ordered regions

and a microstatistical model considering the angular probability distribution of the magnetic moments is constructed to calculate the stress-dependent macroscopic hysteresis-free magnetization strength and magnetostriction. Second

the hysteresis effect is simulated by combining the dynamic inverse J-A model

and the energy dissipation factor R

the scaling factor v

and the stress-dependent magnetization dissipation factor ζ are introduced to realize the accurate simulation of hysteresis characteristics over a wide range of magnetic densities

and to control the permeability at the reversal point of hysteresis and magnetostriction multi-loop reversal. Finally

comparing the simulation and experimental results

it verifies the accuracy of the model.
