Abstract

The fatigue strength problem of multi-deck ship is serious. When in the same external load and nominal stress level, structural fatigue life of the details are closely related to the specific structural forms. Therefore, optimizing the structure of the details could reduce the stress concentration factor of details local structure, and has an important role in improving the fatigue life of details. Based on parametric modeling approach, a method of shape optimization of multi-deck ship structure typical details was studied. In this method, APDL language was utilized to create a parametric model of a typical detail. Stress concentration factor and details shape parameter were respectively taken as the objective function and optimization variables. Computing program was written to achieve anti-fatigue design purpose. According to this method, several typical details were optimized and details structure forms with smaller stress concentration factor were given.
