| 目的 确保弹箱内的弹链(抱弹状态)在库房存放一段时间后依然稳定供弹，描述可散式弹链拉断力在不同温度环境下的变化规律。方法 应用环境作用动力学理论，建立可散式弹链的拉断力变化微分方程，求解可散式弹链的拉断力变化微分方程，得到可散式弹链拉断力变化规律的微分方程通解，再通过高温加速试验数据，求得可散式弹链拉断力变化规律的微分方程通解系数，建立可散式弹链拉断力变化规律模型。选择具体的XX可散式弹链，通过实验室70、90、110、130、150 ℃的加速试验，获取高温加速试验数据。采用粒子群全局优化算法，由高温加速试验数据求得可散式弹链拉断力变化规律通解中的系数，得到XX可散式弹链拉断力变化规律模型。结果 通过海南、江津库内的短期实测数据，与XX可散式弹链拉断力变化规律模型计算结果进行对比，最大误差小于5%。结论 验证了可散式弹链拉断力变化规律模型的有效性。 |

| In order to ensure that the ammunition belt in the magazine can work in normal condition after keeping in the storeroom for a period of time, it is necessary to describe the behavior of the tensile force of the dispersibleammunition belt at different temperatures. In this paper, the tensile force changing differential equation of the dispersibleammunition belt is established based on the theory of environmental action dynamics. The tensile force changing differential equation of the dispersibleammunition belt needs to be solved to obtain the general differential equation solution of the tensile force behavior of the dispersibleammunition belt as well as the general solution coefficient of the tensile force of the belt from the high temperature accelerated test data. Then a model of the tensile force of the belt will be established. The concrete XX dispersibleammunition belt is selected to obtain the high temperature acceleration test data through the acceleration tests at 70, 90, 110, 130 and 150 ℃ in the laboratory. Based on the data of high temperature accelerated test, the coefficients in the general solution are obtained, and the change law model of XX dispersibleammunition belt tensile force is established. Based on the short-term measured data in Hainan and Jiangjin, the validity of the model is verified by the fact that the maximum error is less than 5%. This change law model of XX dispersible ammunition belt tensile force is effeetive. |
