摘要
研究了集中载荷作用下一次超静定等强度梁的最优刚度分布.利用阶梯折算法的思想,给出了目标函数、几何约束条件关于设计变量的显式表达式,并给出算例.
The flexural rigidity optimal distribution of the equi-strength static-indeterminant beam under a concentrated force is studied. Based on the stepped reduction method, the governing equation can be explicitly expressed by the design variables well as geometric constraints. An illustrative examples is also given.
