为了保证发动机正常工作，需要对管路进行保温设计。对管路热环境进行了仿真，利用ANSYS软件编写 APDL 程序，对一定厚度发泡层的空间管路进行了热分析，得到了管路的瞬态温度场。为了减小管路发泡层的厚度，采取在管路外侧利用电流加热；该改进方案在减少了管路重量的同时，也增加了管路的安装空间。该仿真分析为发动机管路的保温设计奠定了基础。

In order to ensure normal work of the engine, the thermal insulation of the engine is needed. The pipeline thermal environment was emulated by the design program which is written by APDL language of ANSYS, and the thermal analysis of spatial pipeline with the specific thickness foam layer was obtained, which gained the transient field of the pipeline. Furthermore, in order to reduce the thickness of the foam layer, the pipeline was heat up by electricity. This betterment not only reduced the weight of the pipeline, but also enlarged the fixing space of the pipeline. The results lay a foundation to the design of the pipeline thermal insulation.
