Nonlinear Vibration Behaviors of Side-Placed High-Temperature Superconducting Bulk and Permanent Magnet System

The vibration properties of a side-placed high-temperature superconducting (HTS) bulk and permanent magnet (PM) system have been investigated theoretically and experimentally. In this system, an HTS pendulum (HTSP) is introduced to laterally arrange the HTS bulks beside a PM with a high pinning force. The resonant frequency nearly linearly decreases when increasing both the mass of HTSP and the gap between superconductors and a magnet. The results indicate that the resonant frequency is dependent on HSTP mass and stiffness. This may be helpful for the future application on close-proximity spacecraft operations and maglev system.
