Finite Element Analysis of Landing Grid Ship Assembly in Vertical Loading Conditions

Abstract

The parts considered for analysis are the Grid and the grid support, which ismounted on the upper deck of the ship. Ship deck is meshed using shell mesh of shell 63. Support pins between the grid and the grid support are modeled as tapered beam of circular cross section as they have different diameter at ends. The support pins are modeled using beam44 element type. The grid is meshed with tetrahedral elements

solid 45 and the grid support is meshed with hexahedral elements solid 45.The grid assembly is to be analyzed for vertical loading conditions and to calculate the stress and the deformation by using FEA Methods.
