The invention discloses a low-resistance ship type design method for an underwater vehicle, which comprises the following steps of: selecting square polynomial linear equations with different parameters to determine basic equations of head and tail line types according to technical requirements; according to the allowable value range of the adjustable parameter and the influence of the change of the adjustable parameter on the linetype characteristic, determining the numerical values of one or more groups of adjustable parameters, and obtaining a preliminary linetype; according to the determined basic geometric parameters of the shape of the navigation body and the obtained line types of the head and the tail, a preliminary and complete shape curve of the navigation body is formed; verifying the preliminarily determined shape of the navigation body, and checking whether the preliminarily determined shape of the navigation body meets design requirements or not; and finally, carrying out multiple times of iterative verification through CFD simulation and related experiments. The low-resistance ship type design provided by the invention can effectively cope with complex flow characteristics such as multi-phase, turbulent flow, phase change and unsteady flow characteristics specific to cavitation and turbulent flow, and further meets the design requirements of stability, maneuverability and the like of the underwater navigation body.
