摘要

为了设计和制造更优越的月球光学望远镜,采用了碳-碳复合材料。介绍了CCC的制造工艺和承载气缸总成的加工工艺。CCC的密度为1.73g/cm3,热膨胀系数为0.5×10-6/℃。对LOT的热适应性进行了分析,采用碳-碳圆柱体将LOT的工作温度提高到-20°C~+40°C。对带有CCC圆柱的LOT进行了有限元分析,结果表明LOT的第一频率为185Hz。对LOT进行了加工和装配。进行了振动试验,试验结果与有限元分析结果一致。试验结果表明,CCC承载缸能够经受住力学性能的考验。所有的分析和测试表明,CCC可以胜任LOT。

Application of carbon-carbon composite for load-carrying cylinder in lunar optical telescope
The carbon-carbon composite (CCC) was applied in order to design and fabricate much more predominant lunar optical telescope (LOT). The fabricating technics of CCC and machining technics of load-carrying cylinder assembly are introduced. The density of CCC is 1.73g/cm3, and the coefficient of thermal expansion is 0.5×10-6/°C. The thermal adaptability of LOT was analyzed, the operating temperature of LOT will be improved to -20°C~+40°C that the carbon-carbon cylinder is used. Finite element analysis of LOT with CCC cylinder was performed, and the results show that the first frequency of LOT is 185Hz. The machining and assembling of LOT have been performed. The vibration testing has been accomplished and the testing results are consistent with finite element analysis. The testing results show that load-carrying cylinder of CCC can stand the mechanical proof. All analysis and testing indicate that CCC can be competent for LOT.
