Strength Analysis of Portable Blast Room Using Modular Glass Reinforced Plastics Wall Panel by Finite Element Method

Abstract

In the shipbuilding and ship repair industry, the most common surface preparation technique used is abrasive blasting. The abrasive blasting and the other surface preparation techniques are the significant sources of shipyard waste and air pollution. The one of any kind techniques to reduce the hazardous air contaminant associated with the abrasive media is blasting room. The abrasive blasting operation is isolated by the blasting room to reduce the exposure to the shipyard environment. The portable blasting room design has been developed using the modular wall panel system. The research is focused on the strength analysis of portable modular blast room using glass reinforced plastics as the wall panels. The research method has two main steps during the strength analysis of the portable blast room. At first, the geometric form of the modular blast room was developed and defined to obtain the finite element model. Secondly, the load and boundary condition was defined, considering the wind load and the structure weight which are exerted to the blast room structure. The displacement method was adopted for the numerical analysis.
