摘要
建立了舰船结构服务性极限状态——总振动可靠性分析的失效极限方程，提出了概率有限元计算公式系统，并引入模糊集合隶属度概念，研究了总振动模糊可靠性分析．算例表明文中提出的方法是有效和合理的．
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.
