摘要
描述了基于ICM方法的结构拓扑优化新模型并应用于骨架与连续体结构。ICM方法意指独立、连续变量与映射变换及其反演。新模型将两种结构统一建立了具有重量目标函数和多工况下应力与位移约束下的优化问题。提出的过滤函数是ICM方法的关键技术之一。
A new optimization model of the structural topology based on the ICM method is described to apply into both skeletonal and continuum structures. The ICM meansIndependent, Continuous variables and Mapping transformation and its inverse. The model has united both structures into a uniform optimization problem with the weight objective function subjected to size constraints, stress and displacement constraints under multiple loading cases, A filter function is proposed to be one of key techniques of the ICM method. The optimization strategies and algorithms are illustrated in the paper.
