Abstract

The stability of the suspension is a key challenge for the application and promotion of electromagnetic suspension technology, especially when it operates in conjunction with a flexible structure, which significantly increases the system's complexity. This paper abstracts the characteristics of the coupling conditions between an electromagnetic suspension system and a flexible structure and designs and constructs an experimental apparatus that includes an electromagnet and a simulated flexible structure with adjustable stiffness and inertia. Based on the Lyapunov method, the central manifold theorem, and the Poincaré method, the stability of the electromagnetic suspension system and the conditions for Hopf bifurcations are derived. Finally, through reasonable experimental design and data analysis, the correctness of the theoretical analysis conclusions is validated, providing references for the engineering applications of electromagnetic suspension systems.

与柔性框架耦合的电磁悬挂系统的稳定性分析：建模、控制、分析和实验。

悬架的稳定性是应用和推广电磁悬架技术的关键挑战，尤其是当电磁悬架与柔性结构一起工作时，系统的复杂性会大大增加。本文概述了电磁悬挂系统与柔性结构之间耦合条件的特点，并设计和构建了一个实验装置，其中包括一个电磁铁和一个具有可调刚度和惯性的模拟柔性结构。基于李亚普诺夫方法、中心流形定理和波恩卡莱方法，推导出电磁悬挂系统的稳定性和霍普夫分岔条件。最后，通过合理的实验设计和数据分析，验证了理论分析结论的正确性，为电磁悬架系统的工程应用提供了参考。
