针对船舶动力装置复杂形状零件模型应用性差的缺陷，研究船舶动力装置复杂形状零件CAE智能仿真方法。利用CAD软件设计船舶动力装置复杂形状零件的几何模型，依据CAD模型数据构建零件的CAE分析模型。CAE软件通过前处理部分定义零件模型的单元属性与材料属性，利用信息元理论划分完成属性定义模型网格，对完成划分后的模型网格实施加载与求解，利用后处理过程分析求解数据，分析结果传送至船舶动力装置模型库内，通过图表方式输出仿真分析结果。仿真测试结果表明，该方法有效构建船舶柴油机曲轴的CAE模型，获取施加10 kN扭转变形力后，柴油机曲轴的受力结果，所构建模型应用于柴油机实际运行时，仿真压力输出结果与实际压力吻合度高。
Aiming at the defect of poor applicability of complex shape parts model of marine power plant, the CAE intelligent simulation method of complex shape parts of marine power plant is studied. The CAD software is used to design the geometric model of the complex shape parts of marine power plant, and the CAE analysis model of the parts is constructed according to the CAD model data. CAE software through the pretreatment part defined parts of the model unit and material attribute, the use of information theory dividing complete attribute definition model grid, for the model grid division finished loading and solving, using the data from the post-treatment process analysis to solve the results sent to ship power plant model of the rolls, output simulation results by way of chart. The simulation test results show that the CAE model of marine diesel engine crankshaft is constructed effectively, and the stress results of diesel engine crankshaft are obtained after 10 kN torsional deformation force is applied. The simulated pressure output results are in good agreement with the actual pressure when the model is applied to the actual operation of diesel engine.
