【摘要】：针对涡桨发动机压气机轮盘止口定心传扭结构配合面过盈量开展研究,为其设计提供理论依据。基于拉梅公式并考虑离心载荷的作用建立套装圆筒的力学模型,利用胡克定律和变形协调方程建立套装圆筒在高转速下配合面过盈量与剩余套装应力、转速之间的关系,进而导出轮盘过盈传扭结构配合面过盈量与扭矩、转速之间的关系,提出一种在一定工况下配合面最小过盈量的估算方法,为轮盘止口定心传扭结构的设计和分析提供了理论依据,具有工程应用价值。
[Abstract]:In order to provide a theoretical basis for the design of turboprop engine compressor disk stop centering torsional structure interference is studied. Based on the Lamei formula and considering the action of centrifugal load, the mechanical model of the cylinder is established, and the relationship between the interference of the fit surface and the stress and speed of the residual set at high speed is established by using Hook's law and deformation coordination equation, and then the relationship between the interference of the fit surface and the torque and rotational speed of the wheel disk interference and torsional structure is derived, and an estimation method of the minimum interference of the matching surface under certain working conditions is put forward. It provides a theoretical basis for the design and analysis of the centering torsional structure at the end of the wheel, and has the value of engineering application.
