导电聚合物驱动器力学模型建立的研究

摘要: 针对自制的三层弯曲型聚吡咯导电聚合物驱动器搭建的实验系统,依据等效悬臂梁理论建立驱动器的力学模型。测量驱动器施加低电压(0~1 V)时的基体弯曲变形量,通过研究驱动器的弯曲位移与电压、力与电压的关系,建立了电压与均布载荷的函数关系式。实验结果表明,电压与垂直方向位移成线性关系,当电压为0.7 V时位移可达到17 mm,并且得到电压与应变的比例因子近似为α=0.013。最后计算驱动器各等分点的理论偏转位移与测量值的偏差,得出最大偏差很小,验证了模型的有效性。

Abstract: We established the mechanical model of the home-made tri-layer bending polypyrrole conducting polymer actuator based on the equivalent cantilever theory. Through measuring the substrate bending deformation when the low voltage (0~1 V) is applied to the actuator and studying the relationships among voltage, bending displacement and power, we established the functional relationship between voltage and uniformly distributed load. The experimental results show that the voltage and the vertical displacement have a linear relationship. When the voltage is 0.7 V, the vertical displacement can reach 17 mm, and the voltage with strain scaling factor approximation α=0.013 is derived. Furthermore, we calculated the actuator's displacement deviation between theoretical deflection value and measured value. Then we find that the maximum deviation is very small, thus verifying the validity of our model.
