摘　　要：结合多目标优化与层次分析法在结构设计中的优点,对滚齿机立柱的设计参数进行改进。文章首先运用CAD软件建立滚齿机立柱的参数化模型,并将其导入有限元分析软件AWB中对其进行动静态特性分析;其次通过灵敏度分析得到影响立柱性能的主要设计参数,同时可视化其对目标函数的响应面;然后将设计参数作为优化设计变量,以质量最小、变形量最小和一阶固有频率最大为目标函数对立柱进行多目标优化,得到优化方案的解集合;最后通过层次分析法确定立柱解集合中的各优化方案权重系数,寻找出最优解。Optimization the design parameter for the gear hobbing column, with the integration of multiobjective optimization and AHP. First, the paper is going to establish its parametric model using CAD software and put it into the AWB where vibration modal and the static analysis are performed. Then use sensitivity analysis to gain the main design parameters which influence the column property most. Mean-while, let the response surface of objective function visual. Furthermore, the multi-objective optimization design of the column is performed with these geometric parameters as the design variables. After all optimum proposals are showed up, using AHP to determine the weighting coefficient, and finally find out the most Pareto-optimal solution.
