摘　　要：针对工程实际中复杂的多目标优化设计问题,常遇到性能目标与设计变量之间不具有显式的函数关系式,难以直接运用优化方法进行设计计算,因此提出基于i SIGHT平台的多目标集成优化设计方法。以主轴箱多目标优化设计问题为例,在i SIGHT平台上集成ANSYS软件并进行建模和分析,采用响应面法构建近似模型,利用邻域培植遗传算法获得多目标优化问题的Pareto最优解集,根据工程实际的不同需求,从中选出最合适的优化方案。In view of the complex muhi - objective optimization problem in actual engineering, the relationship be- tween optimization object and design variables can hardly be expressed by explicit function relation, and it is difficult to be designed and calculated using the optimization method. Then the method of multi - objective integrated optimization design based on iSIGHT playform is proposed. Taking a multi - objec- tive optimization design of the headstock as the example, the ANSYS software is integrated in the iSIGHT playform, and is used to modeling and analysis of the headstock. The approximate model is con- structed by using response surface method. The pareto optimal sets are obtained by using the Neighbor- hood Cultivation Genetic Algorithm （NCGA）, and then design maker can select a solution which suits the engineering best.
