【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。更多还原

【Abstract】 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.更多还原
