This paper outlines the current status for the preliminary structural design of the SPICA payload module. Dedicated studies were conducted for key technologies to enhance the design accuracy of the SPICA cryogenic assembly and mitigate the development risk. One of the results is described for the concept of the on-orbit truss separation mechanisms, which aim to both reduce the heat load from the main truss assembly and isolate the microvibration by changing the natural frequency of the spacecraft., 資料番号: PA1510037000}, title = {Preliminary structural design and key technology demonstration of cryogenic assembly in the next-generation infrared space telescope SPICA}, volume = {1}, year = {2015} }
