Intelligent robots are widely used in a wide spectrum of areas, but the underlying mechanism on the operation of actuated structures has not been fully uncovered. In the present study, we have made a comprehensive investigation on the mechanical behaviors of a hard magnetic disc under the action of a magnet. A new technique for preparing the hard magnetic disc is presented. The configurations of the disc after deformation are recoded, which are consistent with the analytical solutions and the numerical simulation results, and the maximum axial displacement of the disk is up to 2.7 mm. The contact force between the disc and the substrate is also calculated, which matches the experimental result very well. The negative pressure of the disc can cause the rise of water column linked with a reservoir (~9.3 mm), which can be explained by the theoretical model. These findings have important implications in such areas as controllable devices, robotics and high-precision measurement.

智能机器人被广泛应用于广泛的领域，但驱动结构运行的潜在机制尚未完全揭示。在本研究中，我们对磁体作用下硬磁盘的机械行为进行了全面调查。提出了一种制备硬磁盘的新技术。记录了变形后圆盘的构型，与解析解和数值模拟结果一致，圆盘最大轴向位移可达2.7 mm。还计算了圆盘与基板的接触力，与实验结果非常吻合。圆盘的负压会导致与水库相连的水柱上升（~9.3 毫米），这可以用理论模型来解释。这些发现在可控设备、机器人和高精度测量等领域具有重要意义。
