Abstract

The Giant Steerable Science Mirror prototype is being developed to assess the tertiary mirror system of the Thirty Meter Telescope. In this study, a new semi-kinematic coupling design is proposed for the prototype based on three pairs of V-grooves and canoe-like components to allow for high repeatability accuracy under heavy loads. A mathematical model was constructed to estimate the repeatability accuracy using the corresponding measurement results and machining errors. The proposed design was verified by an experiment, and the results were consistent with the mathematical model. Furthermore, the results indicate that the repeatability of the semi-kinematic coupling is sufficient for the requirement.

摘要

正在开发巨型可控科学镜原型，以评估30米望远镜的三级镜系统。在本研究中，基于三对V形槽和独木舟状部件，为该原型提出了一种新的半运动学耦合设计，以在重载下实现高重复精度。利用相应的测量结果和加工误差构建了一个数学模型，以估计重复精度。通过实验对所提出的设计进行了验证，结果与数学模型一致。此外，结果表明半运动学耦合的重复性满足要求。
