摘　　要：分析复杂载荷作用下船体板格结构屈曲强度的影响因素,基于ANSYS软件APDL模块参数化建模,对这些因素进行相关性分析,排除无关参数,保留有关参数,得到屈曲强度的定性表达式。然后变更有关参数,得到不同的有限元模型,通过计算得到不同模型下的屈曲强度,分析大量数据,最终得到屈曲强度的定量表达式。该公式可以在工程上用于复杂载荷作用下船体板格结构的屈曲评估,具有重要的实用价值。The paper analyzes the influence factors of hull plate buckling strength under complex loads. Based on APDL parametric modeling of ANSYS, the correlation analysis is conducted to these factors. The irrelevant parameters are excluded and the relevant ones are reserved to obtain the qualitative expression of buckling strength. Then the parameters are altered to achieve different finite element models. The buckling strength of different models is calculated and large amounts of result data are analyzed. The quantitative expression of buckling strength is obtained accordingly. It can be used to assess the hull plate structural buckling strength under combined loads in engineering, which has high practical value.
