摘要: This study presents fatigue strength assessment of the trimaran platform by spectral approach. Spectral calculations are based on complex stress transfer functions established through direct wave load analysis combined with response analysis. In this study, ANSYS software 3 dimensional linear sea- keeping code AQWA is used to compute frequency vessel at zero forward speed. Finite element global structure performed in utilizing hydrodynamic loads. Hot spot approach selected critical details. A MATLAB program, calculation procedure developed calculate total damage using scatter data North Atlantic. Damage incurred during individual heading direction also calculated and presented means polar diagrams its contribution towards cumulative damage.
