航天器材料空間環(huán)境適應(yīng)性評價與認(rèn)定準(zhǔn)則研究

Evaluation and validation of space environmental applicability of spacecraft materials

  • 摘要: 航天器材料空間環(huán)境適應(yīng)性是指航天器材料適應(yīng)空間環(huán)境的能力，同時又是航天器系統(tǒng)級空間環(huán)境適應(yīng)性的基礎(chǔ)。確保航天器材料空間環(huán)境適應(yīng)性是航天器研制初期重要環(huán)節(jié)。文章首先介紹了航天器材料的空間環(huán)境適應(yīng)性類型；其次列舉了材料空間環(huán)境適應(yīng)性評價試驗標(biāo)準(zhǔn)體系；然后分析了空間環(huán)境適應(yīng)性評價手段與認(rèn)定準(zhǔn)則，包括選材階段的評價試驗、采購和使用階段的驗收試驗以及空間環(huán)境適應(yīng)性的認(rèn)定。文章對我國航天器材料空間環(huán)境適應(yīng)性評價與認(rèn)定工作提出若干建議，為航天器材料選擇和空間環(huán)境適應(yīng)性控制提供參考。

     

    Abstract: The space environmental applicability of spacecraft materials concerns the capability of materials to survive space environments. It is an essential condition of spacecraft reliability under space environments. To ensure the space environment applicability of materials is an important part in the initial stage of spacecraft development. Space environmental simulation testing is one of the main approaches to evaluate the space environmental applicability. Various space environmental effects and the related test standards are discussed; and then the evaluation and validation of space environmental applicability of spacecraft materials are presented. In the end, some suggestions are made for future studies in this area.
