In this study, we aim to probe the self-righting behavior of abalone on a substrate based on experiments and mechanistic analyses. A successful self-righting process of abalone is observed, and its critical condition in theory can be given in terms of the rotation angle. Then, according to the moment balance and potential energy minimization, the required tension force of the abalone foot for self-righting is derived with respect to the rotation angle. The experimental result also shows that in many cases the abalone cannot finish this self-righting process. Then, measurements on the tolerant strength of abalone muscle and tolerant adhesion strength of the foot on substrate are both conducted. It is judged that the abalone muscle is strong enough, which can provide enough tension force, and thus, the self-righting mainly depends on the adhesion area of the foot on substrate. These findings cast new light on engineering new types of biomaterials and devices, such as marine equipment and soft robotics.

鲍鱼从底材上自紧的力学研究

在这项研究中，我们旨在基于实验和机理分析来探究鲍鱼在基质上的自对正行为。观察到一个成功的鲍鱼自扶正过程，并且在理论上可以根据旋转角度给出其临界条件。然后，根据力矩平衡和势能最小化，相对于旋转角度得出鲍鱼足用于自直的所需拉力。实验结果还表明，在许多情况下，鲍鱼无法完成此自校正过程。然后，对鲍鱼肌肉的耐受强度和脚在基底上的耐受粘附强度进行测量。据判断，鲍鱼肌肉足够强壮，可以提供足够的张力，因此，自直主要取决于脚在基材上的附着面积。这些发现为工程新型生物材料和设备（如船用设备和软机器人）的研究提供了新的思路。
