Abstract:

The pick-up process of contactors with double coil structure used in aviation is crucial for their response time and lifespan.A simulation analysis method for the pick-up process of contactors with double coil structure used in aviation is proposed based on COMSOL Multiphysics finite element software.This method enables the calculation of parameters such as coil current,electromagnetic force,contact displacement,and core displacement over time.The feasibility of the proposedmethod is demonstrated by comparing the measured coil current waveforms.

Key words: contactor, dynamic characteristics, pick-up time, double coil structure
