optimization of ship resistance, seakeeping and maneuverability using
SBD technique. Hyunyul Kim and Chi Yang (2010) used KRISO
container ship (KCS) as the initial hull and combined radial basis
function interpolation and Lackenby's method to achieve local andglobal hull form modifications to optimize the total drag at different
speeds. Li (2012) realized hull from modification by changing thecross-sectional area curve of the initial ship, and carried out multiobjective optimization for the speed, wave resistance andmaneuverability of the ship. Bagheri, L., Ghassemi, H. and Dehghanian,A. (2014) used the S60 hull and the Wigley hull as the initial hull to
optimize the peak vertical motion characteristics at different Fr andobtained the optimal ship with the displacement as the design constraint.
Lin Y, Yang Q and Guan G (2019) established an automatic
optimization platform based on the MIGA method in conjunction withthe response surface methodology, and analyzed the hydrodynamic
performance of the samples generated by the RSM through CFD
calculations, and optimized the design for the resistance of the 2.7m
SWATH model at Fr = 0.29. Liu, Wan and Hu (2021) used shifting
and Radial Basis Function (RBF) methods to optimize Wigley shipbased on calm-water wave drag with or without generating bulbous
bow, the results show that the bulbous bow generation method
proposed has potential for the drag optimization of medium and highspeed hulls.

ABSTRACTA submarine usually consists of the main hull and appendages such as
fairwater and rudders. In order to give full play to the submarine's good
resistance and manoeuvrability, the SBD technique is used to optimize
the shape of main hull. The six shape parameters of the main hull canbe changed and regarded as optimization design variable, and the dragand tactical turning diameter are evaluated based on CFD. Furthermore,
the Optimized Latin Hypercube Sampling method and Kriging
surrogate model are adopted to save the computational cost. Then, theMulti-objective Constrained Particle Swarm Optimization algorithm isused to obtain the optimal hulls under several constraints. Finally, theapplicable schemes for different working conditions are given.

INTRODUCTION
Submarine has incomparable navigation advantages underwater due toits good performances including resistance and manoeuvrability, and is
widely used in military and civil fields. Since the main hull has a strong
influence on the resistance and maneuverability of the submarine, theoptimization of the main hull should be prioritized.

Several advancements have been made to the optimization ofsubmarine performance, and achieved good results. Qian and Liu (2011)used the dimensions and the longitudinal coordinates of the control
surfaces are selected as the design variables, the unitary dimensionalhydrodynamic coefficients were calculated and the submarine
maneuverability prediction model was established. Based on theiSIGHT optimization platform, the Multi-objective optimization andSensitivity analysis of the submarine maneuverability objects werecarried out. Kou, Yin, Dong and Zhou (2013) came up with the idea ofoptimizing missile dome for the SUBOFF submarine based on CFD
and iSIGHT optimization platform. With the optimization objective ofminimizing the drag, the optimal missile dome design parameters aredetermined and the variation of the drag with each design parameter isanalyzed. Mora Paz and Tascón Muñoz (2014) combined slender bodyIn the past, researchers often used the empirical mode of "modifyevaluate-re-modify-evaluate" for the optimization of hull form, but thismode has the disadvantages of low efficiency, poor accuracy,
ambiguous direction and empirical dominance, which limit theoptimization process to a certain extent. In order to overcome thelimitations of this empirical mode, a simulation-based design (SBD)
technique has been developed, which has the advantages of highefficiency, large design space and good optimization results. The SBD
technique can be divided into five parts: hull form modification, designof experiment, hydrodynamic performance evaluation, surrogate model
construction and optimization algorithm.
