| 目的 研究武器装备在温度环境试验过程中温度的测量方法和温度平衡稳定的时间。方法 利用直接测量方法对3种典型装备进行温度响应时间测量和分析，找出不同类型装备的传热规律，明确其温度环境试验的作用机理，确定装备的温度平衡时间。结果 通过多项试验测试的数据分析了武器装备温度试验应力的选取，在低温和高温工作试验时，整体温度平衡所需时间应适当延长8~10 h，高温贮存时间偏短，应适当延长4~6 h。结论 在武器装备温度环境试验中，应根据自身性能特点获得装备的真实温度相应特性，在条件允许的情况下，尽可能地敞开武器装备的密闭空间，加快热交换，以缩短达到温度平衡的时间。对于关键及敏感部件，应实时进行温度响应测量，保证试验量级选取的科学合理，为装备环境分析及试验方案的制定提供参考依据。 |

| The work aims to study the method of temperature measurement and the time of temperature balance stabilization in temperature environment tests of weapons. The direct measurement method was used to measure and analyze the temperature response time of three kinds of typical equipment, to find out the heat transfer law of different types of equipment, clarify the mechanism of its temperature environment test, and determine the temperature balance time of equipment. Based on data of many experiment, the selection of temperature test forces for weapons was analyzed. In low temperature and high temperature working test, the times required for overall temperature balance should be appropriately extended by 8-10 hours. The high temperature storage was too short, and should be appropriately extended by 4-6 hours. In the temperature environment test of weapons, the real temperature response characteristics of equipment should be obtained according to its own performance characteristics. When conditions permit, the closed space of weapons should be opened as far as possible and the heat exchange should be accelerated to shorten the time for temperature balance. The temperature response of key and sensitive components should be measured in real time to ensure the scientific and reasonable selection of test magnitude, and provide reference for formulation of equipment environment analysis and test schemes. |
