【摘要】 本文介绍了一种自适应柔性机翼后缘变形控制的方法。该方法中采用了由单个驱动器驱动的分布式柔性结构。该方法的关键问题在于设计一种合适的柔性后缘拓扑形式,使该自适应柔性机翼后缘能够达到精确的变形。文中阐明了柔性结构拓扑优化设计的数学模型,针对自适应柔性机翼后缘概念设计提出了基于变密度法的拓扑优化设计方案。通过一个算例分析了驱动点位置和边界约束等因素对拓扑优化结果的影响。更多还原

【Abstract】 The research proposes a kind of topological optimal design method to design the main load-bearing structure of adaptive compliant trailing edge.This approach uses a special class of mechanisms called compliant mechanisms powered by a single input actuator.The key design issue in this approach is the synthesis of a suitable compliant mechanism for the task.In order to implement this scheme,a topological optimal design procedure for such compliant mechanisms is presented.During the topology procedure variable density method is introduced.The influence of objection and the boundary of finite element is considered.更多还原
