Abstract

The invention discloses a system and a method for simulating starting process states of a propeller and a shaft system, and belongs to the technical field of a ship power system. The system comprises a simulating propeller, a simulating shaft system, an inertial element and a friction force torque applying mechanism, wherein the simulating shaft system is connected with the simulating propeller, and the inertial element is arranged on the simulating shaft system; a thread pitch adjusting mechanism is used for adjusting the thread pitch of the simulating propeller, and the inertial element is used for adjusting the rotational inertia of the simulating propeller and the simulating shaft system and enabling the rotational inertia to be consistent with the rotational inertia of a to-be-simulated propeller and a to-be-simulated shaft system; the friction force torque applying mechanism is used for adjusting the friction force torque of the simulating propeller and the simulating shaft system and enabling the friction force torque of the simulating propeller and the simulating shaft system to be consistent with the friction force torque of the to-be-simulated propeller and the to-be-simulated shaft system. According to the system and the method for simulating the starting process states of the propeller and the shaft system, disclosed by the invention, the simulation on the starting process states (comprising the load and the rotating speed) of the propeller and the shaft system can be realized by adopting the system; meanwhile, by changing the device parameters, the load simulation of a starting process of the propeller and the shaft system in different power levels can be realized.

Description

technical field [0001] The invention relates to a simulation system, in particular to a simulation system for the starting process state of a propeller and a shaft system, and belongs to the technical field of ship power systems. Background technique [0002] The current common propeller simulation device usually uses the load motor as the main body, and its principle is as follows: figure 1 shown. By controlling the armature voltage and current of the load motor (usually a DC generator) (usually the current is controlled by a given voltage), when the shaft speed is ω, the required load torque M is formed on the load motor shaft L . In addition, for the monitored shaft speed ω, the load torque M can be controlled by controlling the voltage and current of the load motor L Press the preset M L -ω curve (propeller characteristic curve) is carried out, so as to realize the simulation of propeller load. [0003] Generally speaking, under the condition that there are clear pr...
