太阳电池阵运输过程的振动环境及可靠性分析

文章分析了一些卫星的太阳电池阵运输数据，结果表明：空中运输和铁路运输的环境优于公路运输环境；运输振动响应主要为低频振动且量级较小，其水平向振动响应明显小于竖直向响应；运输振动响应受路况和车速影响较大；不同减振器的隔振效果不尽相同；太阳电池阵单独运输和装星运输的振动响应量级基本相当。经可靠性分析，运输不会对太阳电池阵产生疲劳损伤。

Vibration environment and reliability analysis of solar array in transportation

The vibration data of the solar array of satellites in transportation are analyzed. It is shown that the environment of the airplane transportation and the rail transportation are better than that of the road transportation. The vibration responses in transportation are primarily of low-frequency and small magnitude, and the lateral vibration responses are significantly smaller in magnitude than the longitudinal responses. The transportation vibration responses are influenced by the road conditions and the speed of the vehicle. The damping performance of the shock absorber varies in different cases, and the vibration response of the solar array transported alone is basically the same as when it is transported with the satellite. Reliability analysis results indicate that transportation will not lead to fatigue damages of the solar array.
