| 摘 要： | 太阳翼是航天器电源分系统的重要组成部分。以刚性基板的固定太阳翼为研究对 象，针对航天器总体方案设计阶段的特点，基于“动-势能驻值原理”，将固定太阳翼等效 简化为附集中质量的悬臂梁，并由此推导出固定太阳翼外弯模态基频的近似解析解，提出了 展开后固定太阳翼外弯模态基频的工程近似方法，为今后航天器总体设计人员提供了简单、 可靠的分析方法。

| Abstract: | Solar wing is one of the most important components in spacecraft. The engineering-approximate method is proposed for the first mode frequency of deployed solar wings without yokes at the stage of the system equivalently assumed to be a cantilever beam with mass particles, and a close-form solution for its first mode frequency is achieved. This solution will provide an easy and reliable analytical tool for the system engineers of spacecraft in future. |
