分析了实验室规模的四自由度电动轮式磁悬浮车辆的阻尼项和刚度项。车辆通过电动车轮在有限厚度的导电非磁板上方同时旋转和平移来产生悬浮力和推进力。利用解析的三维稳态涡流模型推导了系统的刚度和阻尼项，并根据它们对线性状态空间模型的适用性进行了分析。对静态稳定性的影响进行了讨论。
This paper analyzes the damping and stiffness terms of a 4-degree of freedom laboratory scale electrodynamic wheel magnetic levitation vehicle. The vehicle creates both suspension and propulsion forces through the simultaneous rotation and translation of the electrodynamic wheels above a conductive non-magnetic plate of finite thickness. The stiffness and damping terms were derived using an analytic 3-D steady-state eddy current model, and are analyzed based on their suitability for a linear state-space model. The implications with respect to static stability are discussed.
