摘要

摘要：针对空间用磁悬浮飞轮在发射过程需要保护的性能需求，提出了一种基于机构自锁原理的可重复电磁锁机构，针对某型磁悬浮飞轮设计了质量为158克的锁紧/解锁机构，尺寸为45mm×49mm×40mm，建立了锁紧/解锁机构的数学模型；针对地面和空间两种环境，分析了机构在锁紧和解锁过程中锁紧力和解锁力的变化曲线，结果表明最大锁紧力为650N，保持锁紧和解锁状态的力分别为133.8N和-9.4N，可有效实现锁紧和解锁功能，重力对锁紧机构的性能影响很小，并根据某型卫星发射过程中的正弦振动、随机振动和冲击力学试验验证了锁紧机构，从而为磁悬浮飞轮的空间应用奠定了坚实的技术基础。

Abstract

Abstract：Due to the launch vibration environment

the use of locking device is necessary for magnetic bearing wheels. We developed a electromagnetic locking device based on self-locking for our magnetic bearing reaction wheel

the mass of the locking device is 158 gram

and the dimension is 45mm×49mm×40mm. The link created by the locking device can be completely released by the compression spring. The mathematical models of lock and release are established. The curves of the locking force versus displacement and the releasing force versus displacement are given. The force of holding locking is 133.8 N

and the force of holding releasing is -9.4N. The ground environment and space environment are considered in this paper

the effect of gravitation is very small for the locking device. The locking device is tested by the vibration table.
