Abstract :
This paper proposes a method for optimized the Unmanned Surface Vehicle (USV) structure based on a combination of iSIGHT optimization software and the parameterized model of geometry and finite element. The finite element model of the vehicle was established by using the parameterize language (ANSYS Parametric Design Language) of ANSYS based on the study of the material of the USV hull. And then the expected target function, the variables and the boundary condition were selected, the optimized value was obtained by using the multi-island genetic algorithm. Finally, analysis was conducted on the conditions of sagging and hogging of the USV, and the strength of the hull was calibrated. The results proves that it can be reduce the weight of the boat and improve its performance by using this method, under the precondition of meting the strength and the general arrangement requirements.
