摘　　要：对应用于小型蠕动泵中的直线振荡电机进行分析,推导其数学模型,并采用有限元分析方法对同类型的直线振荡电机进行推力仿真,提取动力特性,得到了在不同电流密度和动子位移下的电磁推力,并用数学公式表示。由模型得到的计算结果和仿真结果相吻合,证明了该模型的正确性,并为该类电机的优化设计和控制提供参考。The mathematical model of the linear oscillatory actuator（LOA） applied in pocket peristaltic pumps was deduced and analyzed,the thrust of the LOA was simulated by the finite element method（FEM）,and the dynamic characteristics of the LOA were analyzed.Based on the different current density and different displacement of the mover,the mathematical formula of the magnetic thrust of the LOA was presented.Simulation results are in accordance with the deduced expression of the mathematical model of the LOA,and prove the expression correct.The proposed analytical method is available for the design,control and application of this type of the LOA.
