摘要

支承点的分布对折叠太阳翼动力学特性有显著影响。为了研究压紧点分布对折叠太阳翼固有频率的影响，以典型的单折点支承太阳翼为研究对象，根据能量守恒原理和Rayleigh-Ritz理论推导出点支承单折太阳翼的振动方程和频率方程。研究了四点对称支承太阳翼结构系统的固有动力学特性，并以基频最大为优化目标对其支承点的分布进行优化分析。通过算例分析表明其理论计算结果与有限元分析结果具有较好的一致性。研究结果对太阳翼支承点分布的初步设计提供了理论分析依据。

Abstract

Distribution of supporting point has a significant impact on dynamic characteristics for the folding solar panel. In order to study the effect of supporting point distribution on the fundamental frequencies of folding solar panel, a typical single folding solar panel with four point support is taken as the investigation object. Based on the conservation of energy principle and Rayleigh-Ritz theory, the vibration equation and the frequency equation are established for analyzing the free vibration problem of folding solar panel with points support. The vibration characteristics of the folding solar panel with four points symmetrical support is gained, and Aiming at the maximum fundamental frequency to the support points for optimization distribution is also discussed. The examples show the theoretical calculation results have good consistency with the results of the finite element analysis. The research results could provide a theoretical basis for the preliminary design of supporting point distribution for the single folding solar panel.
