In the paper, the influence of the lamination angle of a composite used in a permanent shaft-sleeve joint on dynamic properties is studied. Structural friction is taken into account in the system wall. Basing on available literature, one can easily determine the global equivalent shear modulus of a laminated shaft. The found modulus can be taken into account while formulating a mathematical model of the system in question. The obtained differential equations of motion were solved using the asymptotic Bogoliubov-Krylov-Mitropolski method giving an equivalent damping coefficient and eigen vibration frequency. Using the obtained values, the equivalent logarithmic damping decrement was calculated as well. Following that, a numerical simulation was conducted in order to investigate the influence of lamination angles on the dynamic characteristics of the considered system. The results of that simulation are presented on graphs.
