根据气囊承载形状变化规律，基于目前通用的假设条件归纳出船舶气囊下水工艺中气囊承载能力计算模型，分析影响气囊承载力相关因素。发现气囊承载力与气囊初始压力和工作高度密切相关；通过模型分析，设定合适初始压力与降低工作高度可提高船舶气囊下水的安全性。研究成果可供船厂在制定合理的船舶气囊下水工艺方案时参考。

According to the change of airbag bearing shape and general assumptions at present, a calculation model is established to analyze the airbag＇s bearing capacity and influential factors in the lauching process of ship. It is found that the airbag＇s beating capacity is closely related to initial pressure and the operating height. Through the model analysis, setting a suitable initial pressure and reducing the operating height could improve the safety of launching ship into the water. Such a research is helpful for the shipyard to arrange reasonable launching schemes.
