The invention relates to a variable-slip berth launching analysis method, which is characterized in that the whole structure of a ship is simplified into a cross-section-free and weight-free elastic beam along the length direction of the ship, a gravity-free beam is adopted to replace an original ship body beam model, a gravity and buoyancy difference mode is adopted to load a gravity-free beam node, and the supporting return force error can be reduced to 1%. The berth launching load automatic loading program can realize the distribution of a plurality of slideways according to the distribution of the slideways, can realize the automatic distribution of the load size, the automatic identification of the load position and the complete matching with launching support return force data, realizes the rapid loading, and improves the working efficiency by 300%. According to the method, a variable-slip-distance underwater load analysis method is adopted, under the condition that the number of slips is not increased, the dangerous working condition is refined, and calculation is more accurate. The block load is replaced by the load envelope value, the requirement can be met by one working condition, and 20 or even 40 working conditions do not need to be calculated like the prior art.
一种变滑程的船台下水分析方法,将船舶整体结构简化成一根沿船长方向的无截面无重量弹性梁,采用一种无重力的梁代替原来船体梁模型,采用重力和浮力差的方式对无重力梁节点进行加载,可以将支返力误差缩小到1%。船台下水载荷自动加载程序可按照滑道的分布实现多种滑道的分布,可实现载荷大小自动分配,载荷位置自动识别,与下水支返力数据完全匹配,实现快速加载,提高工作效率300%。采用变滑程间距的下水载荷分析方法,在不增加滑程数量的情况下,对危险工况进行了细化,使得计算更加准确。采用载荷包络值代替分块载荷,一个工况即可满足要求,不需要像现有技术,计算20甚至40几个工况。
