研究表明，在犀牛甲虫（Allomyrina dichotoma）中，折纸状褶皱在翅翼碰撞中起着至关重要的减震作用。 当翅翼与物体碰撞时，它会沿着褶皱塌陷并在一个冲程内弹回原位。碰撞因此得到缓解，这有助于甲虫迅速恢复飞行。研究人员在扑翼机器人中应用了甲虫翅翼的这种机制，从而使其在碰撞后能够安全飞行。
据了解，休息时，甲虫会折叠并把后翅塞在鞘翅中。为了飞行，后翼通过一系列展开配置展开，这些配置由拍打力被动开启。当翅翼完全展开时，折痕锁定在适当的位置，此后利用平坦的膜片产生空气动力。

Title: Mechanisms of collision recovery in flying beetles and flapping-wing robots

Abstract: At rest, beetles fold and tuck their hindwings under the elytra. For flight, the hindwings are deployed through a series of unfolding configurations that are passively driven by flapping forces. The folds lock into place as the wing fully unfolds and thereafter operates as a flat membrane to generate the aerodynamic forces. We show that in the rhinoceros beetle (Allomyrina dichotoma), these origami-like folds serve a crucial shock-absorbing function during in-flight wing collisions. When the wing collides with an object, it collapses along the folds and springs back in place within a single stroke. Collisions are thus dampened, helping the beetle to promptly recover the flight. We implemented this mechanism on a beetle-inspired wing on a flapping-wing robot, thereby enabling it to fly safely after collisions.
