论文摘要
这项研究介绍了纤维增强的管状导电聚合物(FTCP)执行器的分析模型。 FTCP执行器是在电化学电池中排列的低压驱动的电活性聚合物。按照电路类比,开发电化学模型,该电路类比预测了执行器内部的电荷以进行施加的电压。经验关系应用于两种内部现象,即离子的扩散和机械变形。此外,采用有限变形理论来预测FTCP执行器的阻塞力和自由应变。开发的模型与应用电压的现有实验结果一致。另外,解决了各种电气和几何参数对执行器性能的影响。
This study presents the analytical modeling of a fiber-reinforced tubular conducting polymer (FTCP) actuator. The FTCP actuator is a low voltage-driven electroactive polymer arranged in an electrochemical cell. The electrochemical model is developed following an electrical circuit analogy that predicts the charge diffused inside the actuator for an applied voltage. An empirical relation is applied to couple the two internal phenomena, viz., diffusion of the ions and mechanical deformation. Further, the finite deformation theory is applied to predict the blocked force and free strain of the FTCP actuator. The developed model is consistent with existing experimental results for an applied voltage. In addition, the effect of various electrical and geometrical parameters on the performance of the actuator is addressed.
