| 摘 要： | 在航空机电一体化机箱中,各个元器件的发热会对机箱内部温度场产生影响,而温度场的分布对整个机箱内部元器件的工作性能和可靠性有重要的影响。本文以航空机电一体化机箱为研究对象,应用有限元方法建立机箱热分析模型,运用ANSYS Workbench软件对航空机电一体化机箱进行稳态热分析,得到了机箱实体的温度场分布情况,进而计算出工况1情况下探测器周围的稳态温度为292～298 K,工况2情况下探测器周围的稳态温度为307～318 K,均可满足探测器的工作温度要求。通过机箱的稳态热分析,可以为机箱温度场的预测和机箱内发热元器件结构布局优化提供一定的理论支持。

| Abstract: | Fever of different components in aviation mechatronic chassis has impact on temperature field of chassis,and temperature field of chassis has impact on performance and reliability of the components.In this paper,aviation mechatronic chassis was studied.Thermal modeling of chassis was established by finite element method.Steady-state thermal analysis of aviation mechatronic chassis was analyzed by ANSYS Workbench software to get temperature distribution of chassis.Steady temperature around the detector was calculated as 292~298 K under the first condition,and 307~318 K under the second condition.In both conditions,steady temperature can meet the requirements of the operating temperature of the detector. Steady-state thermal analysis of aviation mechatronic chassis provided theoretical support for the chassis temperature field prediction and structural layout optimization components. |
