摘要: 为了满足空间任务需要,对可折展薄膜天线应用需求非常迫切,且朝着大展收比、高精度化、轻质化的方向发展。提出一种百米级多超弹性铰链抛物柱面天线折展机构,该机构主要由超弹性铰链、三棱柱伸展臂、横向折展肋、同步铰链和索网组成;三棱柱伸展臂能够进行纵向折展,横向肋进行横向二次折展。该机构采用模块化设计,依靠横向和纵向分布的超弹性铰链弯曲变形时存储的弹性势能实现展开和锁定,具有无源驱动的特点。考虑了超弹性铰链和绳索的非线性影响对该机构进行静刚度分析;采用位移坐标分析法和拉格朗日方程,分别建立了横向肋展开、三棱柱伸展臂纵向展开的运动学模型,为抛物柱面天线折展机构的宇航应用提供了理论基础。

Abstract: In order to meet the needs of space mission, the application of deployable membrane antenna is very urgent, and it is developing to the large aspect ratio, high precision and lightweight. A kind of parabolic cylindrical antenna folding mechanism with multi tape-spring hinges is proposed. The mechanism is mainly composed of the tape-spring hinges, a triangular prism mast, the transverse folding ribs, the synchronous hinges and cable net. The triangular prism mast can fold longitudinally and the transverse ribs can fold along cross section. The modular design of the mechanism is based on the elastic potential energy stored at the transverse and longitudinal distribution of the tape-spring hinges when it is flexural deformation. Considering the nonlinear effects of the tape-spring hinges and cable, the static stiffness of the mechanism is analyzed; the kinematic models of the transverse ribs and the triangular prism mast are established by using displacement coordinate analysis method and Lagrange equation, which provides a theoretical basis for the application of parabolic cylindrical antenna folding mechanism.

Key words: deployable mechanism, tape-spring hinge, statics analysis, kinematics analysis, parabolic cylinder
