摘　　要：军用通信方舱的升温速率影响到通信方舱车在严寒条件下的快速反应能力。为了通过有限元辅助设计方法提升通信方舱升温过程设计的效率和精度,对方舱进行了-40℃环境下的升温试验,同时应用ANSYS软件建立了方舱的热仿真有限元模型,完成了方舱升温过程的有限元仿真分析。对比5个监测点升温速率的仿真和试验结果,仿真计算结果的误差范围为6%~22.2%,在工程仿真误差范围之内,验证了仿真模型的合理性和有效性,表明以有限元仿真分析方法辅助通信方舱升温过程设计具有可行性和实用性。The heating rate of the military communication shelter affects the rapid reaction ability of the communication shelter vehicle in cold weather.In order to improve the efficiency and accuracy of the heating process design of the communication shelter by finite element aided design method,the heating test of the shelter is carried out in -40 ℃ environment,the thermal simulation finite element model of the shelter is established by ANSYS software,and the simulation analysis of the heating process of the shelter is completed.By comparing the simulation and test results of the heating rates of 5 monitoring points,it is found that the error range of the simulation results ( 6%~22.2%) is within the error range of engineering simulation,which verifies the rationality and validity of the simulation model.The results show that the finite element simulation method is feasible and practical for the heating process design of the communication shelter.
