| Abstract: |
| 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. |
