Abstract:In this work, the impact of small mistuning on rotor/stator contact interactions is investigated. First, a detailed study of a rotor/stator interaction between the first bending modes and the second engine order is presented in the tuned case. Then, a numerical investigation on the effect of mistuning on the studied rotor/stator contact interaction is carried out. In particular, a stochastic analysis is performed to evaluate the robustness of the interaction with respect to the mistuning level. Simulations are… Show more
“…[12,13,14,15,16,17,18]). A research effort has also been made for the construction of nonlinear reduced-order models allowing for the mistuning analysis of bladed-disk in presence of contact nonlinearities [19,20,21,22,23,24,25]. Moreover, due to technological evolutions that involve lighter materials and thinner blades, the nonlinear geometrical effects induced by finite displacements cannot longer be neglected.…”
