Abstract
In this paper, shock analysis was performed for coarse and fine mesh model using MSC/NASTRAN and ANSYS after substituting the foundation of deck mounted equipment of marine ship for mass-spring system. In order to determine input file in MSC/NASTRAN, dynamic response analysis was also performed using DDAM based on the calculation in the range of low frequency. It was confirmed that the coarse mesh model has the sufficient effective weight in a lower degree mode compared to fine mesh model.
