基于精确参数化定义的复合材料桨叶剖面 扭转刚度计算

Cross-section torsion stiffness calculation of composite rotor blade based on accurate parametric definition

  • 摘要: 在系统地对桨叶结构设计流程、结构分析计算方法进行研究的基础上,通过对桨叶组件参数化定义及桨叶铺层三维几何建模方法的扩展,自动获得各桨叶剖面相关组件的几何和材料信息,并基于闭口薄壁梁理论,给出了复合材料桨叶剖面扭转刚度的高效计算方法.该方法一方面充分考虑了复合材料蒙皮铺层的复杂结构以及梁、肋等组件的细节几何模型,避免了三维几何模型简化误差;另一方面,提出了铺层块、等效厚度以及长厚比概念,并采用解析表达,将模型几何解构完全集成于桨叶设计过程自动完成,十分便于工程应用.实例验证表明:提出的方法能够快速、可靠地完成桨叶剖面扭转刚度计算,显著提高设计分析效率.
