[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.
