The invention discloses a force characteristic measuring device for a stern plate type water-jet propeller model. The force characteristic measuring device comprises a ship body model, a propelling system fixing device, a water-jet propelling system, a force characteristic measuring system and a standard weight calibration device. On the basis of flexible connection of the stern plate type water-jet propeller model and the ship body, the water-jet propeller model is further rigidly fixed through the propelling system fixing device and the rigid piezoelectric type force measuring table, additional external force and shaking of the propeller model are eliminated, the stress transmission path of the propeller model is optimized, and the stability of the propeller model is improved. Additional force generated when water flow impacts an inlet flange of the stern plate type water-jet propeller model is eliminated through the flexible sealing rectifying plate, inflow of the stern plate type water-jet propeller model is rectified, and accurate and direct measurement of force and torque of the stern plate type water-jet propeller model in the x-axis direction, the y-axis direction and the z-axis direction is achieved. The multi-component force characteristic rule data of the stern plate type water-jet propeller can be obtained, and the measuring device is compact in structure, high in measuring precision and high in reliability.
