| 摘 要： | 使用投影法修改由满应力法确定的设计点,这一方法是将满应力方向投影到目标函数等值面上, 减少它的不可行成分,使满应力法得到的最优点更接近于真实点.为了改善结构优化的效率,在得到投影方向后通过一维搜索确定下一个点.最后用两个例子来说明这种方法的效果.

| Abstract: | By means of projection, the direction for modifying the design determined by FSD is projected on the contour of objective function to reduce its non feasible components. This procedure results in an optimal point which is close to the real optimum. In order to improve the efficiency of structural optimization, the next design point is determined through one dimension search after the projection direction is obtained. Two examples are given to show the effectiveness of this method. |
