二硝酰胺铵机械感度的含水量-温度耦合效应
Coupled Effects of Water Content and Temperature on the Mechanical Sensitivity of Ammonium Dinitramide
摘要
Abstract
To investigate the evolution of the mechanical sensitivity of the energetic oxidizer ammonium dinitramide(ADN)un-der varying moisture and temperature conditions,standard tests specified by the Federal Institute for Materials Research and Test-ing(BAM)were carried out in combination with the Langlie-D optimization method.The impact and friction sensitivities of ADN samples with moisture contents of 0,5%,10%,and 15%were quantitatively evaluated at 25,50,and 75℃.The results show that both impact and friction sensitivities decrease significantly with increasing moisture content,although the variation is not simply linear and instead exhibits a distinct stagewise pattern.At 25℃,the limiting impact energy increased from 4 J for an-hydrous ADN to 30 J at 5%moisture content and exceeded 50 J when the moisture content reached 10%or higher.Meanwhile,the minimum friction load increased progressively from 56 N and surpassed the upper measurement limit of the apparatus at 15%moisture content.Further analysis indicates that increasing temperature gradually weakens the desensitizing effect of moisture.At a given moisture content,both the limiting impact energy and the minimum friction load at 50 and 75℃are generally lower than those at 25℃,while the corresponding impact and friction ignition-probability curves shift continuously toward lower stim-ulus levels.Among them,friction sensitivity shows a stronger dependence on temperature.These results suggest that the coupled effects of moisture content and temperature are reflected not only in single threshold values,but also in systematic shifts of the entire ignition-probability curve and the corresponding low-probability risk boundary.关键词
