| 摘 要： | 文章用综合低能辐照试验模拟15年地球同步轨道环境对热控材料S781白漆、SR107-ZK白漆、镀银FEP、OSR片的太阳吸收率退化趋势.有机白漆有严重退化,而OSR和镀银FEP材料退化较少.通过与飞行试验结果比较,证明了本次模拟试验的有效性.通过利用退化趋势的试验数据,应用最小二乘法获得退化数学模型.二次指数退化模型与4种材料退化曲线符合较好.更长试验时间结果可以通过数学模型外推的方法获得.经试验验证,用8年试验数据外推15年数据误差不超过1%.

| Abstract: | GEO environmental degradation trend of 15years on solar absorptance for thermal control coatings such as S781 white paint, SR107-ZK white paint, silvered FEP, and OSR on the outer satellite are simulated by a combined low energy irradiation test. Severe degradation is found in organic white paint while OSR and silvered FEP remain quite stable. By comparison with flight test results, the effectiveness of the simulation method is shown. Based on the degradation trend data, the least squares regression method is used to obtain empirical formulas. The second order exponential decaying formulas are found quite good to fit degradation curves of four kinds of materials. Extrapolation for a longer test time is made and the results are verified. The error of using 8 years test results to extrapolate 15 year degradation is shown to be less than 1% . |
