Abstract |
There are numerous aims in a complete and global military submarine hydrodynamic shape design such as speed, power of agility/sea keeping, performance, stress distribution, impact stability, internal arrangements, applied manufacturing methods, stability, cost and etc. Finding optimal shape in different movement scenarios needs running parallel commercial engineering simulations for all objectives in a CAD/CAE integrated environment. This paper applies the above method to find the optimal local shape of submarine sail with fewer number of design objectives in order to study the effectiveness of modeFRONTIER as a multiobjective design optimisation. Automatic multi-optimization process is done in constant submarine dept position, constant submarine hull shape and constant submarine speed in forward direction to approach minimum hydrodynamic drag force and minimum noise. Result of this research is presented as a new shape of submarine sail which delivers more underwater speed and lower noise. For this project modeFRONTIER couples SOLIDWORKS as a CAD package and ANSYS as a CAE package to create integrated optimisation environment. |
