Abstract

The different folding and storage forms of an inflatable boarding platform will have a direct impact on the deployment effect of the marine emergency evacuation system. This paper proposes different folding and storage methods for an inflatable boarding platform in a marine emergency evacuation system. According to the difference between the fold line and the fold direction, the numerical models of a boarding platform with partial fold, “Z” type fold and inner spiral fold are established. The platform models with three folding modes are simulated by numerical simulation. According to the numerical results of the inflation process, the displacement changes of the inflatable membrane and the surface characteristics of the model are compared and analyzed, and the synchronization of the deployment process of the upper and lower airbags in three folding forms is studied. The deployment characteristics of different folding inflatable boarding platforms in different stages are analyzed. The numerical results are of great reference value to the folding and releasing process of an inflatable boarding platform and its practical design as well as its application in the evacuation system.
