Abstract:The limit state equation for ship general vibration failure is established as a service ability failure mode in this paper. The stochastic FEM formulation for ship general vibration is developed.The fuzzy set and member ship degree concept are introduced to study the fuzzy reliability of ship structure under vibration failure mode. The numerical example shows that the method presented here is effcient and reasonable.
Keywords:fuzzy reliability  member ship degree  stochastic FEM  general vibration
