Abstract

The invention relates to the technical field of ship power system design, in particular to a multi-objective optimization design method for a propulsion system, and electronic equipment. Multi-target comprehensive optimization analysis is carried out by taking shafting transmission efficiency as a key point and taking improvement of shafting alignment quality and improvement of vibration characteristics as targets, shafting power consumption can be reduced, and meanwhile, the shafting alignment quality and the vibration characteristics are both improved; by establishing a calculation model of thrust bearing friction power consumption, radial bearing friction power consumption, sealing friction power consumption and rotating shaft friction power consumption, the transmission efficiency of the propulsion system can be accurately and efficiently calculated; and by adopting the finite difference method and mathematical induction, the calculation result of the friction power consumption is more accurate, and the calculation time of the friction power consumption can be effectively shortened.

Description

technical field [0001] The invention relates to the technical field of ship power system design, in particular to a multi-objective optimization design method and electronic equipment for a propulsion system. Background technique [0002] During the sailing process of the ship, the power output by the main engine is transmitted to the propeller through the long and short shafting through the reduction gearbox, and the thrust generated by the propeller is transmitted to the hull through the thrust bearing on the shafting to realize the mission of propelling the ship. During the power transmission process between the gear box of the main engine of the ship and the propeller, parts with high contact stress such as thrust bearings, intermediate bearings, and stern bearings, as well as some shafting systems operating in water, will consume part of the output power of the main engine. Reduces the power received by the propeller. [0003] For the long shafting of large ships, due ...
