Abstract

According to the requirements of a coaxial space remote sensors

a high-precision truss made of carbon fiber composites was developed to be as the supporting structure between primary and secondary mirrors

and its engineering applications were analyzed. In the manufacturing process

the relevant technological process was explored and the high-precision machining of the structure was realized. Finally

the vibration test

mechanical test and temperature stability test were performed. Based on the optical measurement method

an automatic testing platform was set up and the measurement precision was improved by rapidly repeated measurement and the elimination of artificial factors. The analysis and test results indicate that the high-precision truss only weights 13 kg

the first natural frequency is 119 Hz

and the deformations are less than 4 under the conditions of gravity

10 ℃ temperature rise and 4℃ temperature difference. Furthermore

the flatness of mounting interfaces for each component is less than 8 m in the high lightweight and high stability. The truss has been successfully applied in a space remote sensor

and the design scheme

test scheme and the manufacturing process discussed in this paper can be used as a reference for other coaxial space remote sensors with the same type.
