摘　　要：宏微驱动器是一种大行程高精度精密定位器,在通电的情况下宏动系统线圈产生的磁场一定程度上影响微动超磁致伸缩驱动器的输出速度与输出位移。本文通过COMSOL软件仿真,具体分析研究宏动线圈匝数与输入电流大小对GMA微动输出速度与输出位移的影响。研究结果表明:合理的宏动线圈设计保证了宏动系统在最大输出位移的条件下对微动位移输出误差小于要求的最大误差0.6μm,提高了宏微驱动器的整体定位精度。Macro-micro actuator is a large travel and high positioner,which under the condition of the current macro system coil magnetic field and to a certain extent,micro-motion of giant magnetostrictive actuator output speed and output displacement.Through COMSOL software simulation,macro moving coil number of turns and the size of the input current of GMA micro output speed and output displacement are studied.The results show that the output error of micro actuator is less than 0.6μm under the condition of maximum output displacement,and the overall positioning accuracy of micro actuator is improved by reasonable macro coil design.
