摘　　要：针对电磁飞机弹射系统制动的特点,设计了一种永磁涡流制动装置。对涡流制动力的理论公式进行了推导,将理论推导结果和有限元仿真仿真结果进行了对比,验证了理论推导结果的可用性。以理论公式和有限元仿真结果为支撑,对制动装置的永磁体阵列进行了优化,为永磁涡流制动系统的设计提供参考。A permanent-magnet eddy current brake system was designed for the EMALS. The theoretical calculation expression of braking force was derived and validated by the finite element method. Besides, the permanent-magnet array was optimized in the basis of theoretical calculation expression and the finite element results, which can provide reference for the designing of permanent-magnet eddy current braking system.
