【摘要】：隨著我國(guó)空間技術(shù)的飛速發(fā)展,各航天器的發(fā)射任務(wù)日益增多,各個(gè)系統(tǒng)所需要的連接器和電纜組件種類及規(guī)格也日益多樣化,普通連接器和電纜組件已經(jīng)無法滿足型號(hào)要求,而國(guó)內(nèi)連接器和電纜組件的質(zhì)量可靠性等級(jí)長(zhǎng)期以來都停留在較低的水平,尤其是射頻同軸連接器及電纜組件(以下簡(jiǎn)稱產(chǎn)品),雖然普通軍用等級(jí)產(chǎn)品發(fā)展已經(jīng)比較成熟,但國(guó)產(chǎn)宇航用射頻同軸電纜組件仍有很多空白。本文通過產(chǎn)品失效情況的統(tǒng)計(jì)及分析,并結(jié)合宇航應(yīng)用提出的新要求,對(duì)宇航用產(chǎn)品的設(shè)計(jì)要求進(jìn)行了闡述。在理論分析的基礎(chǔ)上,對(duì)空間適應(yīng)性設(shè)計(jì)、結(jié)構(gòu)設(shè)計(jì)、可靠性設(shè)計(jì)及實(shí)現(xiàn)工藝進(jìn)行分析,并提出相應(yīng)的設(shè)計(jì)方案和工藝方案,主要包括根據(jù)輻照、熱真空釋氣的苛刻條件分析薄弱點(diǎn)及敏感特性,實(shí)現(xiàn)正確選材。并從熱設(shè)計(jì)、防腐蝕、老化設(shè)計(jì)等方面采取措施,以提高其固有可靠性。最后對(duì)產(chǎn)品生產(chǎn)工藝進(jìn)行詳細(xì)分析,找出關(guān)鍵工藝并提出控制措施。產(chǎn)品實(shí)現(xiàn)后制定了詳細(xì)的試驗(yàn)驗(yàn)證方案,對(duì)產(chǎn)品進(jìn)行全面的檢測(cè)和試驗(yàn),包括全性能分析試驗(yàn)、結(jié)構(gòu)分析試驗(yàn)、極限評(píng)估試驗(yàn)及壽命考核強(qiáng)化試驗(yàn)等。所有試驗(yàn)結(jié)果表明該產(chǎn)品具有優(yōu)良的機(jī)械性能、電氣性能及環(huán)境性能,具有較高的宇航空間適應(yīng)性,所有性能指標(biāo)均不低于國(guó)內(nèi)外同類產(chǎn)品,尤其是SMA、TNC系列產(chǎn)品電壓駐波比可以達(dá)到1.25,遠(yuǎn)高于國(guó)外同類產(chǎn)品,達(dá)到了國(guó)內(nèi)領(lǐng)先、國(guó)際先進(jìn)的水平,為其他宇航用元器件系統(tǒng)性開發(fā)奠定良好基礎(chǔ)。
[Abstract]:With the rapid development of space technology in our country, the launching missions of each spacecraft are increasing day by day, and the types and specifications of connectors and cable assemblies required by each system are becoming more and more diversified, and ordinary connectors and cable assemblies can no longer meet the requirements of models. However, the quality and reliability levels of domestic connectors and cable assemblies have remained at a relatively low level for a long time, especially the RF coaxial connectors and cable assemblies (hereinafter referred to as "products"), although the development of ordinary military grade products has been relatively mature. But domestic aerospace radio frequency coaxial cable assembly still has a lot of blank. Based on the statistics and analysis of product failure and the new requirements of aerospace applications, the design requirements of aerospace products are described in this paper. On the basis of theoretical analysis, the space adaptive design, structure design, reliability design and realization process are analyzed. The harsh conditions of thermal vacuum gas release are used to analyze the weakness and sensitive characteristics to realize the correct material selection. Measures are taken to improve the inherent reliability of thermal design, corrosion resistance and aging design. Finally, the production process of the product is analyzed in detail, the key process is found out and the control measures are put forward. After the realization of the product, a detailed test and verification scheme was made, and the product was tested and tested comprehensively, including the full-performance analysis test, the structure analysis test, the limit evaluation test and the life assessment strengthening test, etc. All the test results show that the product has excellent mechanical, electrical and environmental properties, and has higher space adaptability, and all the performance indexes are not lower than those of similar products at home and abroad. Especially, the voltage standing wave ratio of SMA-TNC series products can reach 1.25, which is much higher than the similar products of foreign countries, and has reached the advanced level of domestic and international, which lays a good foundation for the systematic development of other aerospace components.
