摘　　要：为实现100~200 kg级小卫星的压紧和低冲击释放,提出了一种连杆式星箭分离机构的设计方案。依据曲柄滑块机构的原理将连杆与包带相结合,采用记忆合金(SMA)拔销器代替爆炸螺栓进行解锁,通过调节螺栓进行预紧力控制,实现在保证足够锁紧力的情况下兼顾分离冲击小的目标。所提设计方案为小卫星星箭分离机构设计提供了一种新的思路。A design of connecting rod separation mechanism for small satellite is proposed in this paper for the locking and releasing of 100~200 kg minisatllite.According to the crank-slide principle,a clamp-band sepration is connected with a crank-slide structure,a bolt is used to control the pretightening force.A SMA pin puller is used as a lock to reduce the unlocking impact.It offers a new idea for design of small satellite separation devices.
