摘要:为了减少月基极紫外相机的质量并保证相机的二维转动机构在卫星发射、地月变轨及月表着陆过程中受到大量级振动冲击以及月表超大温差环境下能正常工作,设计并研制了基于碳纤维复合材料(CFRP)的照准架结构。首先,设计了基于金属材料和CFRP的不同照准架结构,通过有限元法对不同材料的照准架进行分析对比,证明了CFRP照准架的优越性。温度和力学验证试验表明:基于CFRP的照准架质量小于其它材料的照准架,其刚度和热稳定性能满足极紫外相机环境适应性的要求。

Abstract:To lighten the weight of a lunar-based Extreme Ultraviolet(EUV) camera and to ensure the function of the collimation frame structure of the EUV camera under the conditions of the large level vibration caused by satellite launching, earth-moon orbit transfer, moon landing and the large temperature difference on the lunar surface, a collimation frame structure based on Carbon Fiber Reinforced Plastics(CFRP) is designed. Firstly, different collimation frames are designed based on metal materials and the CFRP, and the superiority of the collimation frame based on the CFRP is verified by finite element analysis. Finally, the experiments on temperatures and mechanics are performed, and the experiment results show that CFRP collimation frame has a lighter weight and its stiffness and thermal stability meet the requirements of environmental adaptation. -
