基于凸包模型评估不确定腐蚀对现役船舶剖面模数的影响

Minimum Sectional Modulus Assessment of Ships in use under Uncertain Corrosion Based on Convex Model

现役船舶都存在船体构件的腐蚀问题 ,由于影响腐蚀的因素很多而且不确定 ,造成腐蚀对船舶总纵强度评估的不确定性。本文基于凸包理论 ,建立了评估不确定腐蚀情况下现役船舶最小剖面模数的数学模型 ,并以现役散货船为例 。

The thesis applies convex theory to calculate the uncertain minimum sectional modulus of ships in use and sets up a convex model of uncertain thickness of ship structural members.Choosing a bulk carrier as a typical example,the paper gets and evaluates the limits of its minimum sectional modulus considering uncertain thickness of ship structural members.
