摘要：

Crashworthiness optimization design of a regular ship fender structure with varying cross section fenders are studied. In this paper, new eight models of multi cell fender are selected to determine the best performance crashworthiness. To calculate the crash performance, non-linear finite element analysis is carried using the explicit ABAQUS. Therefore, this research aims to optimize the crashworthiness indicators of fenders subjected to transverse loads using NSGA II and RBF. From the simulation and optimization results, it is found that fender model 4 has the best performance, however it is recommended to change the conventional fender design.
