摘要
本文详细分析了某多光谱扫描仪结构特点 ,工作环境与受力情况 ,并根据航天器受载特点通过对 G.莱希纳和 B.贝尔契 (德 )提出的结构系统可靠性分析通用方法 (以下简称 G.B法 )进行改进 ,建立了结构主体部分在发射阶段的可靠度数学模型 ,以一次二阶矩法为主要算法对红外扫描仪主体在发射阶段的结构可靠性进行了分析和评估 .
According to the loading feature of the aircraft,in this paper a structural reliability math-mode is offered by the G.B method (which presented by G.Lechner B.Bertsche (Germany) in 1990),analyzed and calculated the structural reliability of the main body of the IRMSS during the launching by using the one- and two-order method as the main tool.
