| الوصف: | The article deals with the modeling the stiffness properties of flange rotor joints, which significantly determine their overall dynamics. Investigation is conducted on the example of flange joint of the compressor shaft and turbine disk in the GTE gas generator. It is noted that the moment stiffness of the flange joint is a nonlinear function of bending moment, the magnitude of which is associated with the rotor deflection due to action of unbalanced forces. It is shown that the value of moment stiffness substantially depends on bolt tightening force, axial force, tensile connection, and contact deformations of the flange surfaces. An analysis of the influence of moment stiffness values obtained for different models of flange connection on the general dynamics of the rotor has showed the necessity to take into account the whole set of factors acting at a place of joint. |
