An automatic iterative design procedure for giant accurate antenna structures with the criterion method is presented. The optimal criterion to minimize the r.m.s of difference in wavelength from the deformed surface under the gravity loading with respect to a perfect paraboloidal surface subject to the constraint of constant weight is reduced by a virtual work formulation. The stress constraint under critical loading conditions and the allowable minimum member section areas constraint are also considerd. Three numerical examples show that the approach is effective, and the optimal design can be reached in four to eight redesign cycles.

本文用准则法建立了大型高精度天线结构的自动迭代设计方法。用虚功法推导了天线结构在自重载荷下以重量不变为约束时相对最佳吻合抛物面的均方误差达到最小的最优准则;在优化中还考虑了最危险载荷下杆件的应力约束以及最小截面积约束。对三个天线的计算表明,此法收敛迅速,一般重分析次数在4~8次就获得收敛的结果。

The optimal design of a six-bar linkage to be used in the main driving mechanism of a gear planer is discussed and treated as a multi-objective problem.To solve the minimax problem in a variable domain, a direct method of exploiting the intrinsic characteristics of the computer instead of introducing parameter constants is presented. To solve such a multi-objective problem, a modified linear weighted sum method with an additional conditional constraint is adopted and examples are provided.
