通信卫星热平衡与热真空深度融合一体化试验研究OA

In response to the problems of long duration and high cost in vacuum thermal test for communications satellite,the differences and intrinsic connections between thermal balance test and thermal vacuum test are analyzed,and a research on the deep integration and unification of thermal balance test and thermal vacuum test for satellite is conducted.The timing,conditions and principles for creating virtual thermal balance test conditions in thermal vacuum test are ex-plored.This integration is achieved by merging the different requirements and purposes of the two types of tests.The feasibility and universality of this approach are verified through the entire satellite thermal test.Compared with the conventional process of existing satellite thermal test,the deep integration and unification of thermal balance test and thermal vacuum test can significantly opti-mize the thermal test process and improve the development efficiency,reducing the duration of satellite thermal test by approximately 30%,and reducing the test economic cost by approxi-mately 20%.It is an efficient and low-cost test method with significant technical advantages in terms of both time and cost.
