采用一种新的优化计算方法--神经网络的模拟退火法,对环形板屈曲的厚度分布进行优化设计.在给定体积约束条件下,利用阶梯折算法和幂级数法,极大化弹性薄板的屈曲载荷,给出了目标函数、几何约束关于设计变量的显式表达式,对内边夹紧、外边夹支及内边固支、外边简支的两种边界条件下径向受压环形板的厚度进行了优化计算.

By adopting a new optimal method of simulated annealing in a neural network, this paper presents an optimal design of the annular plate＇s thickness. Explicit expressions of the design-variables are obtained by using the step reduction method, the powerseries solution and by maximizing the buckling load of a thin elastic annular plate subject to given volume and geometry const...
