Abstract

To ensure that the environmental test condition indicators meet the technical requirements of GJB150A, the work aims to design and simulate a steady-state cold working condition for a certain artillery low-temperature environmental laboratory. The air distribution of the temperature field in the laboratory was studied to determine the optimal air supply mode and the layout of air supply and return outlets. Combined with the theoretical calculation of heat loss under steady-state cold working condition, the optimal air supply velocity was obtained by means of finite element simulation. The rationality of the structural design and the accuracy of the calculated values were verified by comparing the simulation results with the experimental data. Simulation results showed that the temperature range reached the minimum when the air supply velocity was 2.0 m/s, while the temperature uniformity was better and the air distribution was more uniform when the air supply velocity was 1.9 m/s. Under this air supply velocity, the experimental results were basically consistent with the simulation results. The temperature standard deviations of the corresponding measuring points from the simulation and experiment were 0.196 and 0.152, respectively, and the experimental temperature uniformity reached ±0.33 ℃. It is determined that the optimal air supply mode for the artillery high and low temperature laboratory is the side supply and side return mode, and the optimal air supply velocity is 1.9 m/s. Under such conditions, the temperature uniformity is the best and can meet the requirements for low-temperature test conditions specified in GJB150A.
