目的 基于阿伦尼乌斯方程,讨论弹上产品加速贮存试验计算加速因子过程中的正常应力水平,即环境等效温度的计算方法。方法 根据导弹武器考察周期内的贮存使用环境温度数据,利用阿伦尼乌斯方程在加速应力水平下对应于贮存使用环境不同温度点的加速贮存试验时间之和,与在等效温度下的加速贮存试验时间相等建立方程,得出等效温度的计算公式,并用数据计算结果进行对比分析。结果 理论分析和算例均表明,环境等效温度不仅与导弹武器在贮存使用过程中的环境温度及其分布有关,还与试验对象的活化能有关,对加速贮存试验时间的影响很大。结论 在对弹上产品开展加速贮存试验计算加速因子过程中,应根据导弹武器贮存使用过程中的环境温度剖面和试验对象的活化能计算等效温度,作为正常应力水平值。 |

Objective To discuss the method of calculating the nominal stress level, which is also called environmental equivalent temperature, for computing accelerated factor used in the missile products’ accelerated storage life tests based on the Arrhenius equation. Methods The equivalent temperature equation was derived, based on the hypothesis that the accelerated storage life test time under the equivalent temperature was equal to the sum of the test time under the Arrhenius equation’s, where the storage temperature was sourced from the missile weapons’ spot observation. The computation result was compared based on these data. Results According to the theoretic analysis as well as the calculation example, the environmental equivalent temperature was not only related to the missile weapons’ storage temperature and its distribution, but is also influenced by the activation energy of the test object, which had great effect on the accelerated storage life tests. Conclusion Both the missile weapons’ environment temperature profile in storage or usage and the activation energy of the test object should be taken into account when calculating the nominal stress level for the missile products’ accelerated storage life test. |
