Ship propulsion engineering
Ice and Shock calculations
The calculations of components for ships subjected to ice loads require the application of the new regulations of the classification societies. This require the use of the finite element method for the analysis of the resistance of the blades as well as calculations of forced vibrations to evaluate torsional loads of ice.
Warships must be prepared to withstand shock loads generated by nearby explosions. The analysis of these loads on the ship’s equipment is carried out by means of dynamic calculation known as response spectrum analysis, in accordance with the standards applicable by the different navies such as MIL-S-901D, STANAG 4141, NFR-90 Shock standard, DEF -STAN 08-120, etc.
