The main ballast tank is an important component of a submarine submerging and surfacing system. To correctly simulate the working process of a submerging and surfacing system, modeling and simulation analysis of the main ballast tank based on MWorks were carried out. Firstly, the models of water injection system, conventional blowdown system and emergency blowdown system were built using MWorks. Then, the model’s reliability was verified by comparison with CFD simulation results. Finally, the impact of factors such as back pressure and sea opening area on the injection and drainage process of the main ballast tank was analyzed. The results show that the relative error of main ballast tank blowing time between the MWorks simulation results and the CFD simulation results is within 10%; increasing back pressure will increase the blowing time and reduce the structural strength requirements for the main ballast tank; increasing the sea opening area will reduce the filling time, blowing time and the structural strength requirements for the main ballast tank. The main ballast tank system models built with MWorks have fast calculation speed and accurate regularity characteristics, which facilitates the rapid adjustment of engineering design parameters to determine design input.
