起竖系统的优化设计

对起竖系统的优化设计从快速性、受力情况等 方面进行了分析,确定了优化目标.对每个目 标函数进行无量纲化处理,采用传统的线性加权法进行了多目标优化求解.采用均匀试验设 计确定样本点,基于协同仿真获得样本数据,建立了多项式响应面模型,对某起竖系统关键 支点的位置进行了多学科优化.通过构造的评价函数,同传统的多目标优化方法得到的结果 进行比较,分析了2种方法的差异,表明了多项式响应面方法的有效性,为起竖系统的进一 步开发和设计提供了有利的工具. 

Optimum design of erecting system

Optimum design of erecting system was analyzed from the points of view of rapidity and acting force,and the objective function of optimization was established.Each objective function was nondimensionalized,and the multiobjective optimization function was solved by conventional weighting method.Sample point was appointed by uniform design.The polynomial response surface model was set up based on sample experimental data of collaborative simulation.Multidisciplinary design optimization of the position of key pivots on some erecting system was carried out.The polynomial response surface method was compared with conventional multiobjective optimization method through the evaluation function constructed.It shows that the polynomial response surface method is effective by analyzing the difference between the two methods.This method is a favorable tool for further development and design of erecting system.
