Magnetic-Thermo Coupling Model for Cable Tension Sensor Based on Magnetoelastic Effect

Abstract:

Starting with the domain walls changing of magnetization process for the cable tension sensor, the influence mechanism is studied between temperature and magnetization. In this paper, making Jiles-Atherton (JA) model as the theoretical basis and introducing the Curie temperature as additional parameter, a magnetic-thermo coupling model for the magnet elastic cable tension sensor is constructed by analyzing the temperature and the physical parameters of the model, followed that, a mathematical analysis is used for the model as the stress or temperature is changing. Compared the analytical results, the effects of the temperature to magnetization is obvious when the sensors is in magnetization rising or decline stage, and a reasonable magnetization working point not only can reduce the interference but insure the sensitivity to stress changing of the sensor.
