摘　　要：依据电活性聚合物机械能向电能的转换机理,研究电活性聚合物发电原理.采用Mooney-Rivlin模型建立了电活性聚合物变形特性的数学模型,分析了材料在不同状态下的力学特性.并分析了电活性聚合物在静电场中的受力情况,能量收集方程及运动学方程.采用丹佛斯生产的电活性聚合物材料,构建电活性聚合物风力发电机实验平台;通过大量的实验研究,分析实验数据和现象,结果证实了电活性聚合物发电的原理.According to the energy transformation of the dielectric electro active polymer（DEAP） from mechanical energy to electric power,the electric power generation mechanism is studied on the DEAP.The mathematical model for simulating the deformation of dielectric elastomer is set up on the basis of the Mooney-Rivlin model,and the dynamic characteristic of the material is discussed under different working conditions.Meanwhile,DEAP is analyzed in the static-electric field on the forces,scavenged energy equation and motion equation.With the Danfoss DEAP material,the prototype is set up for harvesting energy from the wind.Quantitative experiments and research as well as detailed analysis show that the DEAP can generate the electric energy harvesting from the environmental sources.
