在傅里叶变换光谱仪研制中,基于迈克尔逊干涉仪的动镜机构研制是技术难点之一,而柔性铰链机构则是动镜机构的核心部分。利用简单的平行两杆机构为基体进行复杂化设计,得出一种新型柔性铰链机构并对其进行原理分析,利用有限元分析软件Patran和Nastran对其进行模拟计算,并和传统的平行两杆机构理论计算结果进行分析比较。结果表明,新型柔性铰链机构不仅使动镜的垂直耦合位移量缩小到原来的1.4%,而且将动镜的运动自由度有效地降至一维,为后续研究者提供参考。
In the development of Fourier transform spectrometer, the development of the mirror mechanism based on Michelson interferometer is one of the technical difficulties, while the flexible hinge mechanism is the core part of the mirror mechanism. A simple parallel two-bar mechanism was used as the base to carry out the complicated design. A new type of flexible hinge mechanism was obtained and its principle analysis was carried out. The finite element analysis software Patran and Nastran were used to simulate the structure and compared with the traditional parallel two-bar Institutional theoretical calculation results are analyzed and compared. The results show that the new flexible hinge mechanism not only reduces the vertical coupling displacement of the moving mirror to 1.4%, but also effectively reduces the freedom of movement of the moving mirror to one dimension, which can be used as a reference for subsequent researchers.
