| 目的 利用计算机便捷计算橡胶材料长期贮存过程的累积损伤。方法 分析弹药上使用广泛的4种橡胶材料在长期贮存过程中产生累积损伤的原因和损伤模式，在经典反应动力学方程中引入修正系数，对反应动力学方程进行修正，建立4种橡胶的累积损伤模型。在此基础上，开发一套针对不同贮存环境下不同种类橡胶材料各种性能的累积损伤仿真软件。将软件仿真计算得到的多个牌号橡胶密封圈压缩永久率数据与实际试验测试得到的压缩永久变形率数据进行对比。结果 计算机仿真预示结果与60 d试验实测结果接近，计算偏差在10%以内。结论 该仿真软件预测精度较高，可用于对长贮过程中弹药橡胶材料和其他橡胶材料累积损伤仿真。 |

| The work aims to conveniently calculate the cumulative damage of rubber materials during long-term storage by computer. The reasons and damage modes of the cumulative damage of 4 kinds of rubber materials which used in ammunition during long-term storagewere analyzed. Correction coefficientswere introduced into the classical reaction kinetic equation to correct the reaction kinetic equation and establish a cumulative damage modelfor the4 kinds of rubber. On this basis, a set of cumulative damage simulation software for various properties of different types of rubber materials under different storage environments was developed. The compression set rate data of multiple grades of rubber seal ring calculated by software simulation were compared with the compression set rate data obtained in actual test.The results showed that the computer simulation prediction results were close to the 60 day’s actual test results.The calculation deviation was within 10%. In conclusion, the prediction accuracy is high, it can be used forsimulation of cumulative damage of ammunition rubber materials and other rubber materials during long storage. |
