The experiment apparatus has been developed , which is based on software ( labview ) and hardware ( pci board ni 6024e ) . the displacements and 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 实验选取了不同电压幅值,不同频率的方波、三角波、正弦波三种波形作为电激励信号,利用高速摄像记录ipmc的位移变形,并通过力传感器实测了ipmc试样末端的输出力。

It is concluded that maximum bending displacement becomes larger as the input voltage gets larger and the frequency becomes lower , while the curve of bending displacement is affected by waveform . in comparison with the little effect by various waveforms , the generative force at the tip of the ipmc actuators increases as the input voltage gets larger and the frequency becomes lower 结果表明,电压幅值和频率对其位移变形的大小影响较大,波形对其位移变形的轨迹影响较大;电压幅值和频率对其输出力的大小影响较大,而波形对其输出力影响较小。
