摘　　要：针对电磁轴承设计过程中光轴的质量阵M、刚度阵K以及阻尼阵C的复杂计算问题,根据设计初期和设计后期的需求差异分别采用观察者模式和状态模式,并使用统一建模语言UML对有限元计算所需的M、K、C阵的求解实现进行了面向对象的建模。2种设计模式的组合使用提高了设计过程的灵活性和计算效率。In order to avoid the complexity calculating for the mass matrix, the stiffness matrix and the damp matrix of the axis during the design of the electromagnetism bearing, a pattern of implementation for them was presented. For the different requirement of the earlier design and the later design, the observer pattern and the state patten were used respectively, and UML was applied to construct object-oriented model for them. The combination of the two patterns improves the flexibility of design and the efficiency of calculation.
