Designation and Verification of Manned Spacecraft and Cargo Ship Universal Operating Platform for Vacuum Thermal Test Based on Modular Design

Abstract Before the spacecraft vacuum thermal test, the spacecraft needs to be hoisted into the space environment simulator. Due to the high altitude of the spacecraft, a dedicated operating platform is required. The size of the manned spacecraft and the cargo spacecraft are inconsistent, so the existing operating platforms cannot satisfy the operating requirements of both types of spacecraft. In addition, the existing operating platform has poor structural strength and needs to be assembled in the space environment simulator. In order to solve these problems a universal platform is in proposed. This paper adopts modular design method, using analyzing software for modal analysis, instability analysis and overall lifting analysis. It reduce the maintenance, storage, and transportation costs of the operating platform, improve the assembly efficiency of the operating platform and realize the universal design of the operating platform of the manned spacecraft and the cargo spacecraft.
