航天器热平衡试验方法国内外标准比较分析

Comparison and analysis among domestic and foreign test method standards for spacecraft thermal balance test

航天器环境试验中的热平衡试验是航天器研制过程中必不可少的试验项目和重要程序。GB/T 34515—2017《航天器热平衡试验方法》的编制借鉴国外航天器环境试验最新技术成果,同时将国内航天器热平衡试验工程经验加以总结和提炼,涵盖各试验单位在实践中普遍运用的试验方法,标准条款具有较强的实用性。文章将该标准与相关的国外标准进行对比分析,明确国内外标准的异同,以期为该标准的实施应用和推广提供参考。

Among spacecraft environmental tests,the thermal balance test is an indispensable test item and an important procedure in the spacecraft development process.Chinese technical standard GB/T 34515—2017 Thermal Balance Test Method for Spacecraft is compiled based on the latest technical achievements of foreign spacecraft environmental tests,as well as the domestic engineering experiences of the spacecraft thermal balance test,covering the common test methods used by various test units in practice,with the practicability of its clauses improved.This paper compares and analyzes this standard and the related foreign standards,to clarify the similarities and differences between them,to provide a foundation for the implementation,the application and the promotion of the Chinese standard.
