摘要

摘要: 导管是涡轮叶片冲击冷却的核心部件。为实现复杂冷却结构叶片导管的快速建模,提出了创成式导管快速建模方法。首先应用截形法构建适应叶片内腔几何形状的管身截面线以创建管身,然后应用截交包络裁剪法与特征等弧长阵列方法保证了导管冲击孔与导管突起的建模稳定性与建模效率,并构建了突起定位迭代公式,保证了导管与叶片内腔的配合精度。最后采用UG Open API工具开发了导管快速建模程序,验证了所提方法的可行性。

Abstract: Impingement pipe is the core component of the impingement cooling in turbine blade. In order to realize the rapid modeling of impingement pipe in turbine blade with complex cooling structure, a generative rapid modeling method was proposed.Firstly, the body of pipe was created by section curves which suits the shape of channel in blade and generated by curves created by insect-shape method. Then by using envelope surface trimming method and along-curve array method, the modeling stability and efficiency of cooling hole and hump are guaranteed.And the fitting precision between impingement pipe and blade is guaranteed by an iterative formula about protrude position.Finally, a rapid impingement pipe modeling program was developed based on UG Open API, and the modeling result validated the feasibility of the proposed method.
