本文设计并仿真了IPMC驱动的仿鸟翼扑翼。为了使机翼在扑翼运动中产生升力和推力，机翼必须能够同时扑翼和扭转。对于这种机翼的设计，IPMC致动器的形状需要设计成使得致动器可以在机翼冲程期间产生弯曲和扭转运动。为了确定IPMC致动器的形状，已提出了一个等效的双压电晶片梁模型的基础上测得的力-位移数据的IPMC。采用等效模型和热模拟方法对IPMC驱动机翼进行了数值模拟，确定了IPMC驱动器的合适形状。通过这种方式，我们可以选择一个性能最好的机翼，可以创造最大的扭曲运动在扑翼。
In this work, flapping wings actuated by IPMCs are designed and simulated to mimick birds wing. In order for the wing to generate lift and thrust during flapping motion, the wing must be able to flap and twist at the same time. For design of such wings, shape of the IPMC actuator need to be designed such that the actuator can create bending and twisting motions during wing strokes. To determine the shape of the IPMC actuator, an equivalent bimorph beam model has been proposed based on the measured force-displacement data of an IPMC. The equivalent model and thermal analogy are used for numerical simulation of IPMC actuated wings to determine suitable shape of the IPMC actuator. In this way, we could select a best performing wing that can create the largest twist motion during flapping of the wing.
