| The numerical model of GTE compressor disk ? blades contact system is developed, taking into account centrifugal forces, distributed aerodynamic loads and nonlinear contact conditions. The impact of various loading factors and contact conditions on the stress concentration zones near disk-blade junctions is investigated. Lifetime assessment for structure elements is based on multiaxial fatigue Coffin ? Manson type criteria. |
