应用abaqus与tosca进行优化设计的英文论文
tosca 网站上应用abaqus与tosca进行优化设计的英文论文Optimization of simple linear and advanced nonlinear problems using TOSCA and ABAQUS
“The world is non-linear.” This statement is familiar to all ABAQUS users. In their daily work
there are a lot of problems which are not to be only analyzed, but should be improved or optimized.
This demands the availability of an optimization system which can handle not only simple linear but
also advanced non-linear problems. The optimization system TOSCA with interfaces to industry
standard solvers like ABAQUS offers the capability to treat linear and non-linear problems in an
optimization. Topology and shape optimization of ABAQUS models with an arbitrary number of
load cases and boundary conditions can be performed with TOSCA. A parameterization of the
model is not needed, which reduces the modeling effort and allows greater flexibility in the
optimized structure. Most features of ABAQUS like contact, non-linear material and special 好,优化的文章真是不多阿。 早就听说过TOSCA,但一直没有接触到,能具体介绍一下吗? 优化的软件据说很贵,而且计算规模很大。 不完全对,如果你用过ANSYS WORKBENCh带的优化程序后,就不会这样看了 贴几张图看看,带的例子 Tosca的特点就是 非参数优化,与有限元软件的独立性比较强,做优化分析不需要太多的理论,软件自动化程度比较高。优化结果经过平滑处理可以输入到cad软件里面,也可以用曲面工具修正后再传回有限元软件计算或cad.软件优化设置比较容易。是工程师的理想选择,但就是有点贵。 另外一个例子的图片 又找了好东西! TOSCA从哪弄的?告诉我吧! 网上下载 我还是喜欢几何参数优化的软件
不太喜欢基于单元的
因为优化结果无法直接被设计者使用
Patran2007有个功能就是将一个一个的单元自动光顺
成为光滑的曲面
但也总是觉得不如几何参数优化来的实际
大的拓扑结构优化计算量是很大
以前在Nastran里做过,感觉这方面凸显了计算机的愚蠢
