The fast and accurate computation of the static and dynamic characteristics is the foundation of design and optimization of electromagnetic (EM) relay. This paper, considering the advantages of both the magnetic equivalent circuit (MEC) method and the finite element method (FEM) for the EM system computation, proposes an algorithm of output space-mapping (OSM) based on the compensation factor (CF)...
The vibration performance of hermetically sealed electromagnetic relay which contains armature system is an important element when we judge the reliability of apparatus. A nonlinear single-degree-of-freedom mathematic model considering contact loss was built in this paper, and the dynamic behavior of armature subjected to external Gaussian white noise excitation was investigated by using Fokker-Planck...
Hermetically sealed structure is the optimal style to protect electromagnetic relay (EMR) from formidable working environment. Each product shall be subjected to thermal environment shock in accordance with MIL-STD-202 from -65degC to +125degC temperature, so it is of great importance for thermal analysis of EMR to increase the thermal stability and reliability requirement. In this paper, special...
