文章提出了节点拓扑变量一种非耦合映射的ICM方法,对于结构拓扑优化问题予以建模和求解:首先将基结构划分为由较小单元组成的网格,取节点独立、连续的拓扑变量,建立了一种双线性形函数插值的变量非耦合映射,替代了单元独立连续拓扑...展开更多 文章提出了节点拓扑变量一种非耦合映射的ICM方法,对于结构拓扑优化问题予以建模和求解:首先将基结构划分为由较小单元组成的网格,取节点独立、连续的拓扑变量,建立了一种双线性形函数插值的变量非耦合映射,替代了单元独立连续拓扑变量,使单元的“有”或“无”连续化近似,实现了节点拓扑变量过滤识别与物理量的单元内插值,推导建立了节点拓扑设计变量的优...

An ICM(independent continuous mapping) method with the mapping of node-uncoupled topology variables is proposed in this paper,which is applied to model and solve the structural topology optimization problems.Firstly,the ground structure is meshed into nodes and elements...MORE An ICM(independent continuous mapping) method with the mapping of node-uncoupled topology variables is proposed in this paper,which is applied to model and solve the structural topology optimization problems.Firstly,the ground structure is meshed into nodes and elements.Independent and continuous topology variables are d...
