Reliability Analysis of Door Magnetic Switch under Different Permanent Magnetic Distribution

Abstract:

In order to improve the reliability and safety of door magnetic switch, a mathematical model of three reed switches was designed to satisfy this requirement under different permanent magnetic distribution. To obtain the same magnetic adsorption force for the magnetic reed switch, this paper uses a simulation method based on ANSYS software to mainly analyze the different distribution of three permanent magnets how to affect the adsorption force of door magnetic switch. The simulation results demonstrate that the adsorption force is different for different layout of permanent magnet and help to obtain the installing position of the reed switch and to improve the reliability.
