A multi-parameter model of heat treatment process for soft magnetic materials on performance of HSERs
文献摘要：
Material properties play an important role in the performance of electromagnetic mech-anism.For an aeronautic Hermetically-Sealed Electromagnetic Relay(HSER),more than 50％parts are made of soft magnetic materials.Therefore,the performance of soft magnetic materials directly determines the static and dynamic characteristics of the HSER.Based on the theory of crys-tal recrystallization,this paper analyzes cold extrusion and heat treatment in the processing of soft magnetic materials,simulates the grain change process of an armature at different heat treatment temperatures,establishes a correlation model of temperature,grain size,and magnetic energy,and verifies results by scanning electron microscopy.Results of heat treatment temperatures from 800℃to 920℃are obtained and compared.A sample soft magnetic material after heat treatment at different temperatures has the largest difference in the initial magnetization range,up to 22％.In order to verify the fluctuation of the overall output characteristics of an HSER caused by the dif-ference between soft magnetic materials,a static and dynamic analysis model of a typical HSER is established,and the accuracy of the model is verified by a set of actual test system.The difference of dynamic characteristics under different heat treatment temperatures is nearly 3％.
