Description

Technical Field

[0001] This invention relates to the field of ammunition safety, and more specifically, to a slow-burn test method and system based on real-time prediction of accelerated life testing. Background Technology

[0002] Fire is a common occurrence in modern warfare and one of the most significant factors affecting ammunition safety. When ammunition catches fire during storage, transportation, or combat readiness, the external environment heats up very rapidly. If a fire breaks out in a nearby ammunition depot or workshop, even if the ammunition is not directly exposed to flames, the high-temperature airflow around it can still cause the temperature of the energetic materials inside the ammunition to rise over a long period, potentially reaching the detonation point and leading to a violent explosion.

[0003] To verify the ability of ammunition to withstand near-fire environments, both domestically and internationally, the "heat-combustion" method is commonly used. This test involves heating the ammunition at a constant rate until a reaction occurs, and then measuring the reaction temperature and intensity. This method simulates a near-fire environment, enabling the assessment of ammunition's thermal safety and improving the safety of ammunition equipment entering service.

[0004] This assessment method verified the thermal safety of ammunition, but failed to assess its thermal safety after long-term storage. Ammunition products are typically characterized by long-term storage and single-use. While stabilizers in the energetic materials of ammunition ensure their stability during long-term storage, physical and chemical changes occur over time. For example, propellants may absorb moisture, undergo thermal decomposition, and experience migration and efflorescence of plasticizers or liquid components, crystallization of crystalline compounds, and aging of polymeric components. These changes significantly affect the mechanical and thermal sensitivity of explosives, leading to substantial differences in the reaction of ammunition stored for different durations under fire conditions. Furthermore, thermal safety degrades with increasing storage time, and ammunition may even reach a critical thermal safety state towards the end of its lifespan, increasing safety risks.

[0005] To address the challenges of thermal safety assessment and verification for long-term stored ammunition, improve the accuracy of ammunition safety assessments, and reduce safety risks during ammunition use, this invention presents a slow-burn test method based on real-time prediction of accelerated life testing. This method accelerates product lifespan through a high-temperature environment and conducts real-time prediction of remaining lifespan during the accelerated lifespan process. Upon reaching the end of its lifespan, a simulated fire environment is applied until the ammunition reacts. Using this method for slow-burn testing enables long-term thermal safety assessment of ammunition, improving the accuracy of ammunition safety assessment results.

[0006] Patent document CN108182500A (application number: CN201810104642.4) discloses a method for predicting the reliability of ammunition storage based on accelerated life testing. This method aims to improve the prediction accuracy of ammunition storage reliability and address the problems of high computational load and difficulty in ensuring accuracy for small sample data in traditional prediction methods. The proposed steps are as follows: An improved global particle swarm optimization (IGPSO-BP) neural network model is established for the accelerated life test dataset. The particle positions in the particle swarm optimization algorithm are defined as the weights and thresholds in the BP neural network. The optimized network weight parameters are obtained by finding the optimal particle positions, maximizing the global search capability of the particle swarm optimization algorithm and fully utilizing the local search capability of the BP neural network. An indirect method is used to predict the reliability of ammunition storage. However, this invention does not utilize the measured temperature of the accelerated product test, nor does it comprehensively apply the real-time equivalent life calculation and slow combustion technology to implement product safety testing. Summary of the Invention

[0007] To address the shortcomings of existing technologies, the purpose of this invention is to provide a slow-burn test method and system based on real-time prediction of accelerated life testing.

[0111] Example 3:

[0112] Example 3 is a preferred example of Example 1, and is used to illustrate the present invention in more detail.

[0113] The core idea of ​​this invention is to accelerate the ammunition life by continuously applying high temperature tests during the combustion test. By collecting the real-time temperature of the ammunition, the remaining life is estimated in real time. When it is determined that the remaining life is close to the end, a slow combustion test is started, and the temperature is increased according to the set temperature rise rate until the ammunition reacts.

[0116] The system employs variable factor prediction and conversion, using measured temperature for dynamic real-time lifespan prediction. The conversion factor changes with the measured temperature of the product.

[0117] The slow-burn test employs a step-by-step heating method, with the holding time for each step-by-step heating selected according to the ammunition caliber.

[0118] An assessment of the impact of slow-burning tests on the lifespan of the test products was added.

[0119] The method includes the following steps:

[0120] Step 1: The product lifespan is N0 (years), the time elapsed from the time of passing inspection and entering the warehouse to the present moment is N1 (years), and the remaining product lifespan is N2;

[0136] Step 3: Determine the heating time point. Calculate the lifespan of the slow combustion process as 0.5 years.

[0137] Step 4: Start heating, setting the constant high temperature to 80℃. During the test, sensors deployed on the test product will collect the product temperature in real time.

[0139] Step 6: The control system controls the heating device to heat at a total temperature rise rate of 25℃ / h. The entire heating process is controlled in a step-by-step manner, such as increasing the temperature by 5℃ within 12 minutes.

[0140] Step 7: During the heating process, the temperature of the test product is monitored by multiple temperature sensors. After removing outliers from the multiple temperature sensors, the average value is taken, and the heating device is started and stopped by temperature feedback.
