以船厂自主研制的B型独立液舱为研究对象，通过合理制定水压试验工艺及支撑工装布置开展液舱水压强度试验研究。采用有限元法对该液舱在水压试验过程中的结构受力开展预报，完成有限元预报与现场监测值比较。结果表明，有限元预报值与现场监测值吻合度较高，验证了采用有限元法开展水压试验强度评估的准确性。通过开展参数化分析总结了液舱底部支撑座平整度对局部受力的影响规律，可为类似液舱支撑设计及水压试验工艺实施提供理论支撑。
Hydrostatic test is an important method to carry out quality inspection for the design and construction of independent tanks Taking a Type-B independent liquid tank as the research object, the hydrostatic test procedure and bottom support layout are to be reasonably formulated under the shelving state of the assembly platform in this paper. The finite element method is used to predict the structural stress of the tank in the hydrostatic test process, and the analysis results are compared with the on-site monitoring results. The comparison results show that the finite element results are close to the actual monitoring results. Furthermore, the parametric analysis of the influence of the structural flatness in the bottom supports on the local force of the Type-B tank during the hydrostatic test is carried out, so as to provide theoretical supports for the design of the cargo tank supports, as well as the implementation of the hydrostatic test.
