基于网格变形技术的涡轮叶片变形传递

为实现学科耦合,需要在涡轮叶片多学科设计优化的气动模型和结构模型之间传递温度、气压和变形等载荷.研究结构变形向气动网格传递的实现方法.参数空间插值方法解决耦合面网格不一致时的变形插值问题;网格变形技术用来调整气动网格内部节点的位置,保证变形传递后的网格质量.某涡轮叶片变形传递实例的表明:该方法能够用于多学科设计优化问题中的变形传递.

Displacement transfer with the mesh deformation method in multidisciplinary optimization of turbine blades

A mesh-deformation-based method was provided in transferring structural displacements to aerodynamics meshes for multidisciplinary optimization of turbine blades.The method focuses on disturbing interior nodes of aerodynamics meshes to keep mesh-quality for the deflected blades.The nodes was disturbed as if they are in a deformed solid under displacement loads.This solid represented the interrelationship of nodes of the aerodynamics meshes.A displacement transfer of a turbine blade was provided.The results indicate that the mesh-deformation-based method work well for the displacement transfer.
