载人航天器关键电子产品综合环境应力试验

载人航天器电子产品在轨经历多种环境应力的综合作用,为提高载人航天器电子产品的可靠性,针对其综合应力环境考核需要,制定了载人航天器电子产品综合环境应力试验方案,并设计了试验程序,明确了各单项应力环境试验条件。经筛选,9艘载人航天器共136台电子产品参加了综合环境应力试验。试验结果表明,综合环境应力试验可以有效地暴露载人航天器电子产品设计和制造缺陷。

Combined Environmental Test of Key Electronic Equipments of Manned Spacecraft

Electronic equipments of manned spacecraft subject to various environmental stress on orbit.To strength the reliability of key electronic equipment of manned spacecraft,a scheme of combined environmental test was established and test procedure was designed,which determined the environmental conditions of every single item.136 units of key electronic equipments for 9 manned spacecrafts were selected to participate in the combined environmental tests.The results showed that combined environmental test can effectively expose defects of manned spacecraft electronic equipments design and manufacturing.
