| 中文摘要: |
| 为了满足数据采集设备在水下200 m深度作业时的稳定性和经济性需求,按照压力容器设计准则,在充分考虑了结构强度、材料抗腐蚀性以及工作稳定性的情况下,通过系统化的材料选型和结构优化,设计了一款低成本便携式的聚甲醛材质的数据采集舱。该采集舱通过ANSYS Workbench仿真软件的强度计算和形变分析,发现在安全系数2.5、施加5 MPa的等效静水压力载荷(对应500 m水深)的极限工况中,舱体最大形变量仅为0.99 mm(占外径0.825%),最大等效应力为53.2 MPa,低于聚甲醛的许用应力强度55 MPa。 |

| To meet the stability and economic requirements of underwater data acquisition equipment operating at a depth of 200 m, a low-cost and portable underwater data acquisition capsule made of polyoxymethylene (POM) was designed based on pressure vessel design criteria. Through systematic material selection and structural optimization, comprehensive consideration was given to structural strength, corrosion resistance, and service reliability. Finite element analysis was conducted using ANSYS Workbench to evaluate the capsule's strength and deformation behavior. The results indicate that, under the ultimate condition with a safety factor of 2.5 and an equivalent hydrostatic pressure load of 5 MPa (corresponding to a water depth of 500 m), the maximum deformation of the capsule is only 0.99 mm, accounting for 0.825% of the outer diameter. The maximum equivalent stress is 53.2 MPa, which is lower than the allowable stress of 55 MPa for POM. |
