摘要
就干涉式红外傅里叶光谱仪,研究确定空间微调机构应有的功能特征及其实现方法。按星载应用要求的简单而可靠,设计微调装置结构;并通过对结构扰度的理论分析,用有限元方法对机械结构建模,进行模态、加速度、正弦振动和随机振动的分析,得到满足仪器要求的结果。
To determine the functional character and realizing method of space-borne micro adjusting device through the requirements of interference type infrared Fourier spectrometer. According to the space requirements of simple and reliable structure, micro adjusting device is designed. And through the analysis on immunity theory, the finite element method is used to model the mechanical structure. According to the analysis of modal, acceleration, sinusoidal vibration and random vibration, the results of satisfied the requirements are obtained.
