摘要: 提出了评价空间索杆铰接式伸展臂性能的主要参数,分析研究了空间索杆铰接式伸展臂的主要性能参数与伸展臂几何特征参数的相互关系.推导了伸展臂线密度、收拢率、弯曲刚度和抗弯强度等性能参数的表达式.分析了伸展臂材料特性对伸展臂性能参数的影响,讨论了空间索杆铰接式伸展臂的稳定性问题,分析了局部失稳与整体失稳的条件.基于抗弯强度约束、弯曲刚度和抗弯强度共同约束两种约束模式对伸展臂进行了设计,建立了伸展臂几何参数和线密度与抗弯强度和弯曲刚度之间的关系方程,并将设计结果与美国ADAM(Able Deployable Articulated Mast)伸展臂参数进行了对比分析.

Abstract: The primary performance parameters of the space cable-strut deployable articulated mast was derived which can evaluate the space cable-strut deployable articulated mast performance. The relationship between primary performance parameters and geometrical feature parameters of space cable-strut deployable articulated mast was analyzed and studied. The expressions of line density, packaging efficiency, bending stiffness and bending strength of the mast were derived. The influence of mast-s material character to its performance parameters was analyzed. The stability problem of space cable-strut deployable articulated mast was discussed, and the condition of local instability and global instability was analyzed. The mast was designed based on two constraints modes of bending strength constraint and bending strength with bending stiffness constraints. The relation equations of geometrical parameters and line density of the mast relate with its bending strength and bending stiffness were established. The design results were analyzed and compared with the parameters of the American able deployable articulated mast.
