摘要
在修正的阿伦尼斯公式基础上,提出固体推进剂贮存寿命的整体预测方法和两步回归预测方法。由于修正的阿伦尼斯公式考虑了温度变化对活化能的影响,所以与将活化能看成常数的阿伦尼斯方法相比,文中方法可以更准确地预测固体推进剂的贮存寿命。而且,固体推进剂贮存寿命整体预测方法能将各个老化温度下的固体推进剂试验数据作为一个整体进行统计分析,具有更大的信息量,可以提高寿命预测精度或节省大量试样。
Based on modified Arrhenins formula, an integral method and a two-step regression method for storage life prediction of solid propellant are presented. Because modified Arrhenins formula considers the effect of temperature variation to activation energy, by the proposed methods, propellant storage life can be predicted more accurately, compared with Arrhenins method which considers activation energy as a constant. Furthermore, by integral method, all test data at different aging temperatures can be analyzed as an integration, so the prediction precision of storage life can be increased with the same specimens, or specimens can be saved in the same precision by this method.
