一种拓扑优化方法在机翼可变后缘中的研究
The Study of a Topological Optimization Method on the Adaptive Wing's Trailing Edge
摘要
Abstract
Making aircraft wing variation under different ilying speeds is a key technology ot variable camber adaptive wing. But traditional hinged mechanism makes wing surface have discontinuous changes, then leading to earlier airflow separation. To solve the problem, compliant mechanism attracts much attention nowadays on account of its characteristics at the continuous smooth deformation and the lightweight. According to the trailing's deformation requirements under different flight conditions, with the least distance between actual shape and desired shape as the target, and a load-path-based method is used to make topological optimization in the compliant mechanism. Different from traditional parametric method taking micro structure as parametric object, the method assigns binary pa- rameter to load path, considering the connectivity in the meantime, the optimization result can avoid the hardly achieved problem, such as checkerboard. Combined with examples, using Isight,Patran and Nastran make the simulation analysis, results show that compliant mechanism achieves the deformation requirements.关键词
