| 摘 要： | 考虑梁结构的预应力，导出了结构的应力及其灵敏度公式。同时，结合结构单元应力水平和相对差商，对于带有尺寸和拓扑变量的连续体组合结构优化问题，建立了一套优化准则，在双方向渐进结构优化方法思想的基础上，形成了一种新的拓扑优化算法。最后，算例表明了该方法的正确性和有效性。

| Abstract: | Considering the prestress of beam structures, a set of stress sensitivity numbers for beam and plate structures are derived, where the structural element stress level is combined with the relative difference quotients, a set of optimum criteria for the combined topology optimization problem of continuum structures with size and topology variables is established, and a kind of new topology optimization procedure is formulated based on a bi-directional evolutionary structural optimization idea. The examples are provided to confirm the validity and effectiveness of the proposed method. |
