In order to solve the problem of low accuracy of physical and dynamic characteristics simulation of conventional ship propellers in multi-propeller environment, a simulation study of physical and dynamic characteristics of multipropeller ship propellers was proposed. Based on the construction of the simulation platform for the physical and dynamic characteristics of multi-propeller ship propellers, the simulation algorithm for the physical and dynamic characteristics of multi-propeller ship propellers is introduced to complete the construction of the simulation model for the physical and dynamic characteristics of multi-propeller ship propellers, and the simulation of the physical and dynamic characteristics of multi-propeller ship propellers is realized by relying on the analysis of the dynamic characteristics of heat release and hindered propulsion of multi-propeller The experimental data show that the proposed method can improve the accuracy of simulation analysis by 54.45% compared with the conventional method, and is suitable for the simulation of physical and dynamic characteristics of multi-propeller ship propellers.
