电介质电活性聚合物（DEAP）作为一种智能材料，在能量收集和驱动方面具有广阔的应用前景。对DEAP发生器的理论分析对指导DEAP发生器的优化设计具有重要意义。本文首先研究了DEAP发电机的四个工作阶段以及输入机械能和产生电能之间的能量转换。建立了锥型DEAP发生器的数学模型。在此基础上，通过求解微分方程和代数方程，得到了DEAP发生器的电容、力-位移关系、膜内应力分布和拉伸比等关键问题。结果表明，DEAP发生器的拉伸位移和偏置电压是影响产生电能的量和能量转换效率的主要因素。此外，还对DEAP发生器的失效规律进行了探讨。最后，通过实验验证了该模型的正确性，证明了该模型用于分析锥型DEAP发生器的可靠性。
As a type of intelligent material, dielectric electroactive polymer (DEAP) has shown considerable promise for energy harvesting purposes as well as in actuator mode. Theoretical analysis on DEAP generators is important to guide the optimization and design of a DEAP generator. In this paper, firstly, four working phases of a DEAP generator and energy conversion between mechanical energy input and electrical energy generated have been studied. Then, the model of a cone-type DEAP generator is established. On the basis of that, some key issues of a DEAP generator, such as capacitance, force–displacement relationship, distribution of stress and stretch ratio in the membrane, have been achieved by solving the differential and algebraic equations. It is demonstrated that the stretch displacement of a DEAP generator and bias voltage are the main factors influencing the amount of electrical energy generated and the efficiency of energy conversion. In addition, the failure rule of a DEAP generator has also been discussed. Finally, the proposed model is proved by experimental results, which shows the model is reliable for analyzing the cone-type DEAP generator.
