Simulation of Inductive Wear Particle Sensor

摘要：

According to the on-line monitoring sensor of mechanical devices, the transient characteristics of the magnetic field and induced voltage in the coils during the process of the ferromagnetic wear particle getting through the inductive wear particle sensor were simulated by a 2-D model of finite element method (FEM) built for coils of the sensor using the nonlinear FEM software Jmag Designer 10.4. The material of the coils and particle and input voltage were taken into account. Simulation results reveal the variation law of magnetic density and induced voltage of the induced coil during the particle movement, and obtain the conclusion which is induced voltage of the induced coil is proportional to the turns of induction coil, and is also proportional to the operating speed of the particle. The research results play an important guiding role in the development of inductive particle sensor.
