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.
