摘要
IPMC(ion-exchange polymer metal com-posite)离子交换聚合物-金属复合材料)是一种人工肌肉材料,其较低的驱动电压能产生较大的位移变形,研究了IPMC这种智能材料的输出力特性。实验选取了不同电压幅值,不同频率的方波、三角波、正弦波3种波形作为电激励信号,通过力传感器实测了IPMC试样末端的输出力。结果表明,随着电压幅值的增大,其输出力也增大;随着电刺激信号频率的降低,其输出力也增大;而波形对其输出力影响不显著。
Ion-exchange polymer metal composite （IPMC） is known as a material for artificial muscle actuator. The advantages of IPMC in requiring low activation voltage and the induced large bending strain led to its consideration for various potential application, especially in bio-inspired robotics. The paper studies the generative force of the IPMC actuator. The generative force at the tip of the IPMC actuators were measured with respect to the different voltages, frequents and various waveforms which include square, sinusoidal, and triangular wave. It is concluded that the generative force at the tip of the IPMC actuators increases as the input voltage gets larger and the frequency becomes lower, which can be compared with the little effect by various waveforms.
