摘 要:汽轮机预扭叶片的装配对其整体性能具有重要影响。文章研究了预扭叶片的变形机制,并通过有限元模型进行仿真试验,以验证预扭叶片装配系统的准确性。使用高速相机和压电式冲击力传感器获取人工敲击叶片的工艺参数,并建立相应的数学模型。在软件中调整该模型的参数,设计汽轮机预扭叶片装配系统。最终结果表明,在气源压力范围为0.4 MPa至0.6 MPa时,该装配系统能够产生足够的冲击力以满足装配需求,从而验证了该系统的可行性与有效性。The assembly for pretwisted blades of turbine has significant effect on its overall performance.In this paper,its deformation mechanism is studied and simulation experiments are carried out through finite element model to verify the accuracy of assembly system for pretwisted blades.The process parameters of manually tapping blades are obtained using high speed camera and piezoelectric type impact sensor as well as corresponding mathematical model is established.The parameters of this model are adjusted in software to design the assembly system for pretwisted blades of turbine.The final results indicated that sufficient impact could be generated by the assembly system to meet assembly requirements when the range of air source pressure was between 0.4 MPa and 0.6 MPa so that feasibility and effectiveness of the system were verified.
