| Abstract: |
| 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. |
