对开式艏门的结构优化改装设计

对开式艏门作为某型船的关键设备在波浪载荷下容易损坏。文章阐述了采用模型试验、理论计算、规范计算、实船试验等方法研究艏门波浪载荷，进行艏门有限元建模计算，从而找到薄弱环节并进行优化改装设计的方法。

Structural optimization and modification design on split bow door

As a key equipment on a certain type of vessel, the split bow door is liable to damage. With methods such as model test, theory calculation, rule calculation, real ship test and etc. , this paper studies the wave load on bow door, makes finite element model calculation of bow door, to find out the weakness for further optimization and modification.
