Driving system based on transient starting process of axial flow pump and optimization method thereof

The invention discloses a driving system based on the transient starting process of an axial flow pump, and belongs to the field of hydraulic machinery and the field of underwater driving. The device comprises an inflow pipe, an axial flow pump, a high-pressure flow pipe, a driving pipe, a driving object and an outflow pipe. According to the method, only a single fluid medium is involved, and cooperative operation of the axial flow pump serving as a power source and the whole driving system and performance prediction of the driving system are achieved in the driving process. Meanwhile, the driving system can meet different initial driving conditions. For a strong transient process with very short driving time, the performance of the axial flow pump can still be accurately predicted in the transient process by establishing the relation between the steady-state characteristic and the transient characteristic of the axial flow pump. The transient starting process of the axial flow pump in the driving process is
