摘要
由于电磁轴承具有传统的机械轴承所无法比拟的优点,现已应用于人工心脏的设计中。在最新的设计中,应用了一种较特殊的电磁轴承。本文通过建立这种电磁轴承的数学模型,研究了该种轴承在偏离平衡位置的情况下的回复力与回复力矩特性,初步分析了其稳定性,为人工心脏电磁轴承的设计提供基础。
Because it has many advantages that the traditional mechanical bearing does not have, now the magnetic bearing has already been used in the artificial heart. In the latest design, a special magnetic bearing was used. This paper mainly studies and calculates the restoring-force and restoring-moment of the magnetic bearings and analyses their stability when they are off the balance point.
