摘要
提出了改进的 FASS( Fatigue Assessment of Ship Structures)评估系统 ,使之适用于液化石油气 ( L PG,Liquified Petroleum Gas)船船体结构的疲劳寿命校核。该系统从疲劳分析的基本原理出发 ,以疲劳累积损伤度公式为理论基础 ,可对船体结构进行疲劳寿命校核。通过对 165 0 0 m3 LPG船的验算 ,表明改进后的方法能有效评估 L
A fatigue assessment system of ship structure (FASS) is proposed from basic theory of fatigue analysis and cumulative fatigue damage formula. FASS can estimate the fatigue life of ship structure subjected to wave loads. The improved FASS is adapted for life assessment of LPG ship structure for the most dangerous spots in ship structure. By the example of a 16500m 3 LPG ship, it is indicated that the modified method can effectively evaluate the fatigue life of LPG ship structure.
