摘　　要：月球着陆器在月面进行高温工况着陆时,已展开的太阳翼须承受着陆冲击载荷,若基板损坏,则电能供给将减少或丧失,影响探测任务的顺利进行。为了对高温着陆工况下太阳翼基板的强度进行验证,文章提出将着陆冲击载荷转换为静态载荷,用高温静力试验对基板强度进行等效验证的方案。该方案基于着陆冲击力学分析结果和着陆过程温度预示结果,在高温下将冲击载荷等效为静态载荷施加在基板试验件上,完成强度验证。利用月球着陆器太阳翼基板对方案进行验证,结果表明:该方案可以获得在给定温度下基板能够承受的最大载荷,以及在给定载荷下基板能够承受的最高温度,因此方案合理可行,可用于太阳翼基板的强度验证。The deployed solar wing of a lunar lander will be subject to landing impact when landing on the moon in high-temperature landing condition.If the substrate is damaged,the energy supply will be reduced or even lost.In order to verify whether the substrate can withstand the landing impact,a test scheme of equivalent verification by converting the landing impact into a static load is presented.It is based on landing impact analysis and temperature indication.The scheme is verified by using the solar wing substrate of lunar lander.The result shows that the proposed scheme can obtain the maximum load of the substrate at given temperature and the maximum temperature of the substrate at given load.So the scheme is reasonable and feasible,and can be used for solar wing substrate strength verification.
