研究了由多个基本立方超导块材组成的磁轴承。本文旨在将具有不同性能特征的多个基本立方体块体集成在一起，并通过设计它们的排列来控制磁场特性。如果能够控制这种磁场特性，那么就可以推导出磁轴承的最佳配置。在本文中，我们的目的是控制磁轴承与多个基本单位立方块和控制的变化，在磁特性的轴承表面通过布置设计。我们进行了通过组合轴承表面的结构布置图案来最小化浮动旋转体的旋转轴线的倾斜角度的最佳布置的计算。我们构建了一个三行三列的正方形布局模型，并通过优化计算计算了布局模式。然后，用这种布置模式构造立方体，并且使用激光传感器测量浮体的旋转轴的倾斜度，并与计算结果进行比较。此外，还测量了悬浮体与支承面之间的距离和悬浮力。我们确认，通过最佳布置抑制旋转角的倾斜是非常有效的，表明控制悬浮力的可行性。
Magnetic bearings composed of multiple basic cubic superconducting bulks were investigated. This paper aimed to integrate multiple basic cubic bulks with different performance characteristics and to control the magnetic field properties through design of their arrangement. If this magnetic field characteristic can be controlled, then the optimum configuration for a magnetic bearing can be deduced. In this paper, we aimed to control magnetic bearings with a plurality of basic unit cubic bulks and to control variations in the magnetic characteristics of the bearing surfaces via the arrangement design. We performed calculations of the optimum arrangement that minimizes the inclination angle of the rotation axis of the floating rotating body by combining the structural arrangement pattern of the bearing surface. We constructed a model with a three-row, three-column square arrangement and calculated the layout pattern via an optimization calculation. The cubic bulk was then constructed with this arrangement pattern, and the inclination of the axis of rotation of the floating body was measured using a laser sensor and compared with the calculation result. In addition, the distance between the bearing surface and floating body and the levitation force were measured. We confirmed that suppressing the inclination of the rotation angle through the optimum arrangement was highly effective, indicating the feasibility of controlling the levitation force.
