CSR-H纵向不平衡力引起弯矩影响研究
|
摘要
该文主要研究CSR-H中关于船体梁载荷的计算及调整方法,针对其未考虑的纵向不平衡力引起的弯矩,提出新的修正公式并用理想模型对修正公式进行验证,同时对纵向不平衡力引起的弯矩进行分析研究,结果显示CSR-H对纵向不平衡力引起的弯矩影响有欠考虑,但是在调整过程中对此偏差进行了弥补,使得对于大多数工况,其船体梁载荷的最终值到达目标值。
The calculation and adjustment of the hull girder loads in CSR-H are studied in this paper.A new modified formula is proposed with consideration of the neglected bending moments caused by the longitudinal unbalanced forces,and is then verified by the ideal model.At the same time the bending moments caused by the longitudinal unbalanced forces are analyzed and studied.The results show that the moments caused by the longitudinal unbalanced forces are insufficiently considered in the formulas of CSR-H,however,the error is remedied in the adjustment process,resulting in that the ultimate loads of hull girder reach the target values under the most operation conditions.
