International audienceThis article presents a methodology dedicated to the vibration analysis of turbomachine blades accounting for both geometric nonlinearities and nonlinear blade-tip/casing contacts in a numerically efficient way through the use of reduced order models. Contact is numerically handled with Lagrange multipliers and the equation of motion is integrated forward in time using an explicit central difference time integration scheme. Nonlinear internal forces caused by large displacements are evaluated using the stiffness evaluation procedure. Three reduction techniques are compared in this article, namely a nonlinear extension of the Craig-Bampton method, the proper orthogonal decomposition and a modal derivatives-based approac...
