摘要
Involute spline couplings are widely used in the aircraft gas turbine engine rotors. In the rotor dynamics problems, they are usually simulated by a link connecting the shafts. Rigidity characteristics of such a connection depend on a set of factors: forces acting from the connected shafts section leading to the shafts distortion in the spline coupling; torque transmitted by the splines; gaps between the splines; friction forces in the contact pairs. Taking into account all these factors is quite labor-intensive even in the finite element formulation. In addition, spline coupling is a nonlinear element, which characteristics depend on the engine operating mode. The paper presents an analytical model making it possible to account for all operating factors of a spline coupling. The model was verified using the finite element calculations.
