文专注于电致驱动纸的机电特性进行研究。电致驱动纸结构能够在相当低的电压下以较低的功率消耗,产生比较大的弯曲位移变形。电致驱动纸是一种复杂的各项异性材料,目前还没有对其进行广泛的定量特征化分析,在电致驱动纸能够应用在驱动器结构之前还要进行基本的机电性能测试与分析。经计算电致驱动纸的杨式模量的变化范围为5～8GPa。热机械分析被用来确定由于去水化以及最大应用温度而影响尺寸变化程度的因素。通过测试样品的关键特性,提供一种测试该材质疲劳特性的一种方法。基于频率的电阻抗分析和介电特性测试也是分析者确定电致驱动纸的电特性。最后利用测试并计算样品顶部的位移大小、阻滞力以及消耗的电功率,来检验电致驱动纸的性能。
The paper focuses on the electromechanical properties of electrodrive paper. Electrically driven paper structures are able to dissipate at a relatively low voltage with lower power, resulting in a greater deformation of bending displacement. Electrically driven paper is a complex and anisotropic material. At present, it has not been widely used to quantitatively characterize it. It also needs to carry out basic electromechanical performance testing and analysis before the electrodrive paper can be applied to the structure of the driver. The Young’s modulus of the electrodrawing paper was calculated to vary from 5 to 8 GPa. Thermomechanical analysis is used to determine the factors that affect the degree of dimensional change due to de-hydration and maximum application temperature. By testing the key features of a sample, a method of testing the fatigue properties of the material is provided. Frequency-based electrical impedance analysis and dielectric properties testing are also the analysts determining the electrical characteristics of electrodrive paper. Finally, the performance of the electrodrive paper was tested by testing and calculating the magnitude of the displacement at the top of the sample, the retarding force, and the electrical power consumed.
