| 摘 要： | 利用离子聚合物人工肌肉(IPMC)固有的电致动性能,设计了圆盘形、S形、条形及扇形4种不同结构的致动膜,选择最优结构的驱动膜以驱动微泵。制备了一系列IPMC悬臂梁状致动器,利用激光位移传感器测出不同条件下致动器产生的位移。ANSYS软件下,利用位移推导出IPMC单元体的弯矩,以此计算衡量微泵的体积变化和最大工作压力。同时,分析了泵膜形状、半径、厚度、驱动电压对泵体积变化和工作压力的影响。结果表明:较之于其它3种泵膜,扇形泵膜的体积变化量最大;泵膜半径的增加有利于增大体积变化量;泵膜厚度的增加有利于增加工作压力;适当地增加驱动电压,可同时提高其工作压力和体积变化量。

| Abstract: | Four types of ionic polymer-metal composite(IPMC)-based diaphragms with disc,S,strip,and sector shapes,were designed for fabricating micro water pump.A series of IPMC-based cantilever actuators were prepared,and their actuation displacements were determined by a laser displacement sensor.Using ANSYS software,some parameters of a pump such as withdrawal volume and working pressure were simulated by changing the radius,thickness,and shape of IPMC diaphragm and driven voltage,and the related bending moments we... |
