摘　　要：针对某新型GEO卫星与其他航天器的对接过程,设计了一种卫星对接装置。该对接装置主要采用空间凸轮机构,首先对其进行详细结构设计,并建立空间凸轮曲线的数学模型,通过理论计算分析空间凸轮机构传动特性。制造样机进行试验验证,通过高速摄影对凸轮机构传动特性进行记录。通过对比表明,试验结果与理论结果高度吻合,验证了空间凸轮曲线数学模型的合理性以及对接装置的可行性。对接装置具有碰撞接触力小、锁紧力大、运动平稳可靠等优点,能够有效地满足GEO卫星对接任务的要求。For the docking process of a new GEO satellite and other spacecraft,a satellite docking device is designed. The docking equipment mainly adopts a space cam mechanism to realize docking and releasing of satellites. First,the detailed design of the docking device is carried out,and the mathematical model of the spatial cam curve is established. The speed and acceleration curves of the spatial cam mechanism during the transmission process are obtained through theoretical calculation. On this basis,prototypes are manufactured for test verification,and high speed photography is used to record the transmission characteristics of the transmission parts of the cam mechanism during the docking process. The experimental results show that the theoretical results are in good agreement with the test results,and the rationality of the mathematical model of the spatial cam curve and the feasibility of the docking device are verified. The satellite docking device with spatial cam curve has the advantages of small contact force,high locking force and smooth and reliable movement. It can effectively meet the requirements of GEO satellite docking mission.
