| 摘 要： | 以灵敏度分析理论为基础,将模糊数学综合评判理论应用于多学科优化设计变量的选择与评价。以某集装箱船为例,在建立了包含静力学、模态分析和动力学的多学科优化时设计变量选择的模糊评判数学模型之后,综合考虑了应力、位移、固有频率、速度和加速度等参数对设计变量的影响。分析表明,该方法简便易行、结果可靠。

| Abstract: | The fuzzy comprehensive evaluation process is used to select and evaluate the design variables in multidisciplinary design optimization(MDO),which is based on the sensitivity analysis theory.A MDO design of the container ship is used to build a model,which includes static analysis and model analysis.The influence of the effects of stress,displacement,natural frequency,velocity and acceleration of structure is considered.The results show that the model is feasible and reliable. |
