船舶气囊下水运动受力计算与校核

Force Calculation and Check of Ship Launching by Airbags

在气囊下水过程中,如何计算气囊受力变化情况,保证气囊下水的安全性一直是一个亟待解决的课题。分析了船舶气囊下水过程,研究了在移船过程中气囊布置数量、间距、所受压力以及承载力的变化,并以某型船为例,进行了气囊受力计算,校核了气囊压力,论证了下水的安全性。

It remains an urgent task to find a way to calculate the force changes of the airbags during the launching process so as to ensure the safety of the ship. This paper analyzes the process of ship launching by airbags and studies the influence of airbag quantity and spacing on pressure variation and bearing capacity variation; and takes a certain type of ship as an example to calculate the force and check the pressure of the airbags so as to prove the safety of the launching process.
