电动力水下航行器电池舱工作环境恶劣，在设计中必须考虑电池散热对整体结构的影响，避免因局部应力过大导致结构件损坏。本文首先确定某型水下航行器电池舱热传导、热辐射和热对流分析数学模型，并基于有限元仿真软件Ansys构建有限元模型；在相应热载荷下，分析舱段温度分布、安装板处最大变形、应力等，验证了结构设计的合理性。本文研究方法具有较好的通用性，结构设计对水下航行器电池舱结构布局具有借鉴意义。
Battery cabin of electric underwater vehicle works in a bad environment. The influence of battery heat dissipation on the overall structure must be considered in the design to avoid structural damage due to excessive local stress. Firstly, the mathematical model of thermal conduction, radiation and convection analysis for a certain type of underwater vehicle battery cabin is established, and the finite element model is constructed based on the finite element simulation software Ansys. Under the corresponding thermal load, the temperature distribution of the compartment, the maximum deformation and stress at the installation plate are analyzed. The results verifies the rationality of the structural design. The research method in this paper has good universality, and the structural design has reference significance for the structural layout of underwater vehicle battery compartment.
