Structural Design and Analysis of Telescope for Gravitational Wave Detection in TianQin Program

Space gravitational wave detection, which could help humanity explore the mysteries of the universe, is a significant objective in the scientific world today, and several different countries and scientific groups have organized programs targeting its realization. The telescope for gravitational wave detection is a crucial component in the detection satellite, as it is the means of receiving and transmitting the interferometric laser beam; therefore, its structural design is very significant. This paper focuses on the telescope in the TianQin program. First, a structural design scheme is given based on a five-mirror optical system Then, some of the component’s parts are refined to improve its mechanical performance. Finally, a mechanical simulation analysis is performed to verify its reliability and feasibility during the rocket launch. The results reveal that the presented structural design scheme for the telescope is both safe and viable.
