磁保持继电器的稳健性参数设计

Robust parameter optimization of magnetic latching relay

随着磁保持继电器的普遍应用,其稳健性也受到越来越多的关注.对于继电器电磁系统的设计,一直以来都仅仅是以保证它的输出特性为最好进行设计的,并没有考虑噪声因素造成的其性能的波动.通过利用ANSYS和ADAMS软件针对某型号三相磁保持继电器进行动力学仿真,找到触头分断速度与时间之间的关系.提出了以3个触头分断速度作为目标函数对该继电器电磁系统进行多目标参数优化设计.通过信噪比和灵敏度方差分析确定各个参数类型,并找到了最佳参数水平组合,这对提高磁保持继电器的稳健性具有重要意义.

With the widespread application of the magnetic latching relay, the robustness of the magnetic latching relay has received more attention. The relay electromagnetic system has always been designed to ensure its optimal output characteristics, and it has not considered the performance fluctuation caused by the noise. By using ANSYS and ADAMS software, the dynamic simulation of a three-phase magnetic latching relay was carried out to seek the relationship between the contact breaking speed and time. The paper proposes a multi-objective parameter optimization design for the electromagnetic system of the relay with three contact breaking speed as the objective function. The parameter types were determined by the variance analysis of signal noise ratio and sensitivity, and found the best parameter combination, it is important in improving the robustness of the magnetic latching relay.
