Research on Optimization Design Method of Nano-Microcrystalline Soft Magnetic Hermetically Sealed Electromagnetic Relay Based on Wavelet Principal Component Analysis

For the hermetically sealed electromagnetic relay (HSER) and other load-sensitive electromagnetic components, combined with the high-performance, low-density characteristics of nano-microcrystalline magnetic materials, the introduction of wavelet principal element analysis method, to get the dynamic characteristics of the strong correlation of the high-frequency principal element components of the time-domain distribution, which is used to optimize the design of the target-looking characteristics. Combined with the lightweight requirements of the small-looking characteristics, the electromagnetic finite element-dynamics model two-way coupling simulation as a calculation basis, using Monte Carlo-based Taguchi method to design the replacement scheme and dynamic characteristics, quality comparison, parameter optimization, and finally get the core replacement-based optimization design scheme, and the actual fabrication of nano-microcrystalline magnets HSER, to build a test system, prototype test results proved that the optimization The prototype test results proved the effectiveness of the optimized design method, and the HSER prototype realized the weight reduction of the electromagnetic system while ensuring the improvement of the dynamic characteristics.
