Parametric Modeling of Torpedo Shell Structure Based on APDL

Modeling Torpedo shell structure is very important to torpedo overall design as well as shell structure optimization. The traditional torpedo shell structure modeling method establishes model with GUI via CAD drawing software, how ever once some parameters change, designers have to rebuild the model from the very beginning and result in waste of design resources. This paper presents a parametric modeling method for the torpedo shell structure based on the ANSYS parametric design language (APDL), with which remodeling can be automatically performed by computer through simply changing a few design parameters. The present method can save much design resources and facilitate the later torpedo shell optimization.
