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 gradient side-move method has already been used to solve the optimization problem of the large scale structures with about 450 variables. If the variables of the structure are in different order of magnitude, the convergence of the optimal computation may be very slow. This paper provides a simple and effective linear transformation which can convert the original problem into a new optimization problem with variables of same order of magnitude in the design space, and hence the gradient side-move method...

The gradient side-move method has already been used to solve the optimization problem of the large scale structures with about 450 variables. If the variables of the structure are in different order of magnitude, the convergence of the optimal computation may be very slow. This paper provides a simple and effective linear transformation which can convert the original problem into a new optimization problem with variables of same order of magnitude in the design space, and hence the gradient side-move method can be effectively used to solve the problem of the optimal design of the thin-walled structures.The trial step length method is usually used to the one-dimensional search, but it requires about 6~10 times of structural re-analysis for converging to the constraint (surface). In this paper, a quadratic interpolation function is used to approach the constraint surface, and the number of structural re-analysis can be reduced so that the gradient side-move method can be more efficiently used to the structural optimal design.

梯度侧移法已经能够解决450个变量的大型结构优化问题~[4]。但是直接用于薄壁结构的优化设计时,由于设计变量具有不同的数量级,收敛极慢。本文提出一个简单而有效的线性变换,使得这类问题变成新的设计空间中设计变量有相同数量级的优化问题。从而使梯度侧移法可适用于薄壁结构的优化设计。 在进行梯移和侧移的一维搜索时,一般采用步长试探法,需要6~10次结构重分析,才能收敛到约束边界。本文用二次函数逼近各个约束边界,一维搜索次数的减少,使梯度侧移法更为实用。
