Оптимизация прямоугольных ребристых пластин с ограничением первой частоты собственных колебаний при управлении высотой и шириной поперечного сечения рёбер

Abstract

The presented algorithm of optimization of rectangular ribbed plates at a predetermined first natural frequency. As control parameters are taken the width and height of the rectangular cross section of the ribs. Formulated new property of optimality by varying the height and width of the cross section of the ribs. Based on the property of optimality is composed of the iterative algorithm has a stable convergence. The examples show that it can be obtained a substantial saving of material.
