摘要
胶粘剂越来越多地应用于武器系统中,其贮存过程中的老化现象是影响武器系统可靠性的重要因素。为研究自然贮存环境中胶粘剂的老化现象,通过使用灰色关联分析法,量化分析复杂灰色系统中不同环境因子与胶粘剂老化现象的关联程度。利用自然贮存试验中胶粘剂老化现象数据,计算各贮存周期内胶粘剂老化速度数据,再结合相应贮存周期内环境因子的统计数据进行灰色关联分析。研究结果表明:试验中四种环境因子对胶粘剂老化速度影响程度从高到低依次为温度、日照时长、湿度和降雨量,与理论定性分析的结果相符。该方法能很好地反映环境因子对胶粘剂性能退化的影响,可为今后进行胶粘剂环境试验提供理论依据。
Adhesives are more and more used in weapon system. The aging phenomenon during the storage is an important factor affecting the reliability of weapon system. In order to study the aging phenomenon of adhesives in natural storage environment,the correlation degree between different environmental factors and the aging phenomenon of adhesives in complex grey system was quantitatively analyzed by using grey correlation analysis method. The aging data of adhesives in natural storage test were used to calculate the aging speed data of adhesives in each storage cycle,and the grey correlation analysis was carried out with the statistical data of environmental factors in the corresponding storage cycle. The results showed that the influence of four environmental factors on the aging rate of adhesives were temperature,sunshine duration,humidity and rainfall from high to low,which was consistent with the results of theoretical qualitative analysis. This method could well reflect the influence of environmental factors on the degradation of adhesive performance,and provide theoretical basis for future environmental testing of adhesives.
