| 摘 要： | 探讨了修正缩减基法（ＭＲＢＭ）在超大型船舶肿剖面纵向构件直接设计法中的应用，将船舯一个舱段模型化为空间的板、壳、杆单元的组合，采用有限元法计算船体结构摧力，并用修正缩减基法优化结构尺寸，使之恰好满足规范规定的强度和稳定性条件，最终得到船体结构构件的最佳尺寸。

| Abstract: | The application of the modified reduced basis method on the direct design method of longitudinal members in very large tanker is discussed.A cabin in midship is modelled as the spaced composed structures with beam elements,plate elements and shell elements,and calculated using the finite element method.The modified reduced rasis method is adopted to get the minimum dimensions of longitudinal members that satisfy the requirement of longitudinal strength according to the DnV rule |
