中文摘要:研究了介电型电活性聚合物(DEAP)的机电耦合特性,分析了电场作用下DEAP的受力情况,结合超弹性理论建立了DEAP的非线性机电耦合本构模型。对电场作用下圆形结构DEAP驱动器的变形行为进行建模研究,给出Yeoh形式的DEAP本构方程、平衡方程和边界条件。通过求解微分方程组得出DEAP驱动器薄膜中的主延伸率和主应力分布,同时分析了预拉伸率、驱动器主动区域面积及激励电压对驱动器变形的影响。利用试验研究了电激励下的圆形驱动器变形行为,试验结果与理论分析比较吻合,从而验证了本构模型的正确性。研究表明:预拉伸率取值为3~4比较合适。

Abstract:In order to study the electromechanical coupling characteristic of dielectric electroactive polymer, the force analysis of DEAP under electrical field was performed, and the nonlinear electromechanical constitutive model was presented by combing the hyperelastic theory. On the basis of the model, the mechanical behavior of circular actuator was discussed. The Yeoh form of DEAP constitutive equation, the equilibrium equations and the boundary conditions were given. Thus, the principal stretch ratio and principal stress in the membrane of DEAP actuator were obtained by solving the differential equations. At the same time, the influences of pre-stretch ratio, the area of active region and actuation voltages on deformation of actuator were analyzed. And the experimental results for deformation behavior of circular DEAP actuator under voltage actuation were consistent with the theoretical analysis results. It was found that the optimal pre-stretch ratio was 3~4. 

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
