摘要
Abstract
As an important part of the propulsion device,the gear transmission system can still maintain good dynamic characteristics in the mode switching process,which has an important influence on the safety and maneuverability of the ship structure.In this paper,the combined drive helical gear transmission system of a ship is taken as the research object,the pure torsional dynamic model of the system is established,and the MASTA software is used to verify the correctness of the model.Based on the model,the dynamic characteristics of mode switching process between single drive mode and combined drive mode were analyzed.And the model is used to find the optimal speed and input torque of the mode switching,and the influence of the meshing stiffness and the torsional stiffness of the shaft on the mode switching process is explored.The results show that the optimum speed of gear 1 is 2250 r/min,and the optimum input torque of gear 7 is 3100 Nm.When the meshing stiffness increases 1～1.2 times,the vibration of each gear pair can be reduced at different switching stages.As long as the torsional stiffness of the shaft is more than 0.8 times of the base torsional stiffness,the vibration degree of each gear pair in the system will not change significantly.关键词
