摘要

摘要: 盘绕式伸展臂是一种空间伸展臂,可用于太阳电池阵、太阳帆、探测臂等空间伸展机构.它有2种展开模式:逐层展开和螺旋展开.以三角形横框铰接盘绕式伸展臂为对象,分析了以逐层展开模式伸展的原理.首先,由于斜拉索不可伸长,导致横杆在伸展臂变形过程中会发生弯曲,并有一个最大弯曲形态.通过在MSC.ADAMS中建立盘绕式伸展臂模型进行仿真计算,可以得到横杆刚度对伸展臂展开过程的影响.以此工作为基础,提出判据:纵杆对第2层横杆的压缩能力和横杆的抗弯能力决定了伸展臂的展开模式,利用相关仿真模型,对这一结论进行了验证.最后,用弹性细杆的Kirchhoff动力学研究了纵杆变形,得到了伸展臂构型参数和展开模式之间的规律.该结果可以作为盘绕式伸展臂设计阶段的参考.

Abstract: The coilable mast is a kind of space mast, and it can be used as many deploying mechanisms such as solar array, solar sail and detecting arm. The coilable mast has two deploying modes: local coil mode and helix mode. Based on the coilable mast with triangle-batten-form and hinges, the principle of the local coil mode was described. Firstly, because of the constant length of the diagonals, the batten deforms and has a maximum deformation. Then, after construction and simulation of the model in MSC.ADAMS, the effect of the batten bending stiffness was studied. With that work, this conclusion was obtained: the deploying mode is decided by two factors: the compressed ability of longeron on the batten of the second layer and the bending resistance of batten. This conclusion was verified with simulation of the coilable mast model in MSC.ADAMS. After analyzing the deformation of longeron using the Kirchhoff dynamics of thin elastic rod, the relation between the design parameter of coliable mast and the deploying mode was obtained. That result is helpful in the coilable mast design.
