基于分断动能的小型密封电磁继电器过负载能力提升方法
|
摘要
过负载能力是衡量小型密封电磁继电器性能的一项重要指标。航空、航天等应用环境的多样化,对该类型继电器提出了更高的过负载要求。基于GJB65B设计了产品实验,通过分断电弧拍摄与动态特性测试,分析了典型小型密封电磁继电器触簧分断速度对于继电器分断能力的重要性。针对传统的反力提升方法存在的弊端,提出了新的分断动能分析法,建立了分断动能计算模型。基于分断动能分析法对某型号典型小型密封电磁继电器进行产品改进,针对释放过程提出了基于折返簧片设计的动能提升改进思路。建立了继电器静态特性有限元模型与动态特性动力学虚拟样机模型,计算验证了该方法的有效性。试制了基于分断动能分析法的改进设计继电器,并进行了过负载实验,验证了该方法的有效性。
As one of the important components of the electronic systems,the requirements for the overload capacity of the small hermetically sealed relay(SHSR) is rising with the development of the multi-application in aerospace field.The experiments for SHSR based on GJB65 B is carried out,and the arc and dynamic characteristic is analyzed firstly.There exist some disadvantages for the improvement using the force-velocity improve method:anti-vibration performance decrease,operate voltage rise and so on.In order to solve these shortcomings,a novel break kinetic energy method(BKEM) idea is presented in this paper to improve the overload capacity of SHSR.The BKEM is established,and the new structure of the spring and the contact system of the relay have been improved according to this method.The FEM model for electromagnetic system and the dynamic model for contact system are built,then simulate the effect for the improved design,therefore carry out the comprehensive improvement of the resisting surge capacity.Overload tests are carried out to examine the correctness of this method in practice.Compared with the original design of the SHSR,the validity of the BKEM method for resisting surge performance improvement has been verified.
