摘　　要：为优化磁保持选针器的选针性能和求解选针最佳驱动参数,利用Ansys作为数值分析工具,建立磁保持选针器仿真模型,通过对比在脉冲电压驱动下,选针器刀头摆动运动规律及转矩变化规律的仿真结果和实验结果,验证仿真模型的合理性;在此基础上,就半硬磁铁芯关键参数对选针性能的影响进行了仿真研究,结果表明剩磁和矫顽力的增大会提高选针速度,但矫顽力的增大会降低选针启动速度。搭建了选针器性能测试实验平台,通过全面实验法分析了驱动电压与脉冲宽度对选针性能的影响因子,得出电压为24 V、脉宽为300μs时为驱动关键点。In order to optimize the performance of the magnetic latching needle selector and get the optional driving parameters of the needle selection,Ansys was used as a tool of numerical analysis,and the simulation model of the magnetic latching needle selector was established.The simulation and the experiment results of the oscillating motion law and the torque variation low of the bit of the needle selector under the driving of pulse voltage were compared,and the rationality of the simulation model was verified by the experiment.On this basis,the influence of the key parameters of a semi-hard magnetic core on the performance of the needle selector was investigated.The results show that the increase of remanence and coercivity will increase the speed of the needle selection,but the increase of coercivity will reduce the starting speed of the needle selection.On the other hand,a test platform for the performance testing of the needle selector was set up,the performance of the needle selection factors driving voltage and pulse width were analyzed by comprehensive experimental method,and the drive key point was obtained when the voltage was 24 V and the pulse width was 300μs,which provides a reference for the actual driving parameters.
