| Abstract: |
| 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. |
