摘　　要：为提高收缩/扩散管无阀微泵的性能,设计了磁力驱动式无阀微泵,并利用ANSYS软件对微泵的整流部件收缩/扩散管和单腔微泵整体结构进行流体仿真,得到了微泵的结构优化参数。仿真和实验结果表明,流量随着管长、最小宽度、扩张角、泵腔半径的增大存在极大值。磁驱动微泵的流量在驱动电压12 V、驱动频率为25 Hz时达到最大值。In order to improve the performance of diffuser/nozzle micropump,a valveless micro-pump driven by magnetic force is designed.Fluidic and magnetic simulation is done by ANSYS software to get optimal structural parameter of diffuser/nozzle and single chamber micro-pump.The simulation and experimental results show that the flow rate has a maximun value with the increase of the pipe length,the minimum width,the divergence angle and the pump chamber radius.When the driving voltage is 12 V and the driving frequency is 25 Hz,the magnetic drive micro pump reaches the maximum flow.
