摘要
利用阶梯折算法,研究了集中载荷作用以及几何约束条件下,二次等强度超静定梁的体积优化设计.用实例给出了在集中载荷作用下等强度梁与等截面梁的体积对比.
The volume optimal design of an equi-strength two degree static-indeterminant beam subjected to a concentrated force and geometry constraint is studied by means of the stepped reduction method. The volume ratio of the equi-strength beam and the cross-section beam under a concentrated force is given by examples.
