摘要
随着航空航天事业的日益发展,为满足运载火箭发射时一箭多星的目标,研发平面天线卫星展开机构的需求愈发迫切,该文设计一种将天线折叠在卫星主体单面上的平面天线展开机构。首先结合天线展开需求,采用新型齿轮连杆铰链,确保天线面板在展开运动过程中不会与其他构件发生冲突,其次绘制出机构简图对自由度进行计算,确定驱动装置的个数和位置,最后应用Solidworks软件建立平面天线展开机构的实体模型,分析天线面板在运动过程中的运动特性。仿真结果验证该机构可以实现天线面板顺利展开的目标。
With the increasing development of aerospace industry,in order to meet the goal of multiple satellites in the launch of a carrier rocket,it is more and more urgent to develop a planar antenna satellite deployment mechanism.In this paper,a kind of planar antenna deployment mechanism is designed,which folds the antenna on one side of the main body of the satellite.Firstly,according to the requirements of antenna deployment,a new type of gear connecting rod hinge is adopted to ensure that the antenna panel will not interfere with other components in the process of deployment.Secondly,the mechanism diagram is drawn to calculate the degree of freedom,and the number and position of driving devices are determined.Finally,the solid model of planar antenna deployment mechanism is established by Solidworks software,and the motion characteristics of antenna panel in the process of motion are analyzed.The simulation results show that the mechanism can achieve the goal of smooth deployment of the antenna panel.
