Abstract

The application is a kind of ship magnus stabilizer optimization platform considering variable diameter ratio. The platform firstly passes through parameter input module, is used for obtaining parameter information required for subsequent module to carry out certain processing, is transported to corresponding working mode, and is finally output to lift calculation module and platform simulation module. Secondly, the lift calculation module introduces the variable cross-section radius change expression, carries out hydrodynamic analysis on the variable diameter cylinder stabilizer to obtain its theoretical lift change rule. Then, the platform simulation module receives the information input by the above module and simulates the hydrodynamic characteristics of the stabilizer with different variable diameter ratios. Finally, the decision analysis module compares and analyzes the simulation results and gives the lift correction parameters and verifies the rationality of the critical point selection. The application expands the analysis scope of the hydrodynamic performance of the stabilizer, reduces the calculation error, enriches the model construction, and realizes the optimization analysis of the stabilizer under different working conditions.
