[优化][ABAQUS][Midas2Abaqus] Topology Optimization of a clamped-clamped beam by Abaqus [两端固支梁拓扑优化分析算例]

做个简单的优化小例子,后续有时间继续再做深入研究吧。这些都是拓扑优化届最初级最初级的小例子。很多书本都可以看到。 先从最简单的拓扑优化开始。后续陆续分享一些实际工程的优化案例,贴近工程的一些优化思路及软件开发应用案例。 【1】Midas Gen Model 【2】Midas2Abaqus Model 【3】Abaqus Model 【3】Optimization Results 优化目标:刚度最大化。 约束条件:体积优化 50%。 (1) Step 5 (2) Step 10 (3) Step 25 (4) Strain Energy 到25步后,结构基本稳定。可以看出优化后的结构的轮廓。 后续再继续深入研究。 注释 ( Comments ) …

[结构分析]Midas Gen 风洞荷载的施加

[结构分析]Midas Gen 风洞荷载的施加,来源于www.jdcui.com, 崔济东,崔济东博士。Midas Gen中风洞荷载可以通过风荷载工况的附加荷载进行施加。若通过这种方式施加,则必须首先定义楼层属性,风荷载将直接施加到相应的楼层。但如果模型较为复杂,比如存在多塔,则楼层划分可能十分复杂。
