由于深海高压环境的特殊性,设计3种无人潜航器电池舱方案,并对其使用性能进行对比。基于Ansys Workbench对3种方案电池舱在4 MPa的工况下进行有限元仿真分析,选取最优设计方案,并利用水静压试验对电池舱体进行可靠性验证。研究结果表明:对于端盖内测加强筋高度和端盖高度不一致的结构特点,采用端盖高度由边缘向圆心位置递减的设计方案,既能够减轻舱体的重量,又能够有效地降低舱体承受的最大应力;在水静压为4 MPa的工况下,电池舱体的最大应力值为206.82 MPa,最大变形量为0.71679 mm。在4 MPa的水静压试验后,舱体外观无损坏,此电池舱体的可靠性满足实际需求。对电池舱的有限元分析和水静压试验,为水下耐压舱体设计提供了一种新的设计方法。
Due to the particularity of deep-sea high pressure environment, three underwater submersible battery cell schemes are designed and their use performance is compared. The finite element simulation analysis of the three schemes under 4 MPa is Ansys Workbench, the optimal design scheme is selected, and the reliability of the battery module is verified by hydrostatic pressure test.The results show that the design scheme of decreasing end cover height from the edge to the center and the maximum pressure is 206.82 MPa, the maximum deformation is 0.71679 mm. After the 4 MPa, the reliability of the battery module meets the actual requirements.Finite element analysis and hydrostatic pressure test of the battery cell provide a new design method for the underwater withstand ballast body design.
