基于比例微分优化准则的拓扑优化方法
A Proportional and Differential Optimality Criterion Method for Topology Optimization
摘要
Abstract
Based on optimality criterion method, a proportional and differential optimality criterion(PDOC) method was proposed and applied in topology optimization design. Since the phenomenon of low efficiency and overshoot caused by the uncertain deviation, this method introduced the proportional and differential control to improve the iteration operator, and constructed more reasonable iteration formula to accelerate the convergence. A new algorithm was utilized to calculate the density distribution of new material, so the trend of deviation can be predicted and corrected in advance. Finally,experimental results indicate that PDOC method is feasible and efficient.关键词
