摘要

摘要具有高残余磁通密度的硬磁软材料在软机器人和生物医学领域具有潜在的应用前景，逐渐引起研究人员的关注。在这项工作中，我们重点研究了硬磁软材料的动态响应。动态运动方程由欧拉-拉格朗日方程导出。研究了在不同方向的力和外加磁场作用下，方位无线电对硬磁软长方体非线性振动的影响。振幅-频率曲线表明，纵横比也对初级谐振的频率和振幅有影响。此外，为了消除不期望的振动响应，将PID控制器应用于硬磁软材料的振动，可以获得期望的结果。图形摘要

Dynamic analysis and active control of hard-magnetic soft materials

ABSTRACT The hard-magnetic soft materials which can sustain high residual magnetic flux density gradually attract the attention of researchers because of potential applications in soft robotics and biomedical fields. In this work, we focus on the dynamic response of hard-magnetic soft materials. The dynamic motion equations are derived by the Euler-Lagrange equation. The effects of the aspect radio on the nonlinear vibration of the hard-magnetic soft cuboid under the force and applied magnetic fields in different directions are investigated. The amplitude-frequency curves demonstrate that the aspect ratio also has an influence on the frequency and amplitude of the primary resonance. Moreover, to eliminate undesired vibration responses, the PID controller is applied to the vibration of the hard-magnetic soft materials, and the desired results can be obtained. Graphical abstract
