Dynamics Analysis of Reversible Turbine Switching Mechanism
In order to improve the reliability of the switching mechanism in the gas turbine and to ensure the maneuverability of the ship,the dynamic characteristics of the switching mechanism are studied,and the influence of the clearance value and the working load on the motion law of the baffle is analyzed by the motion simulation method.The study found that the baffle rotation deviation has a linear relationship with the gap width,and the influence of the gap gradually weakens during forward to reverse switching.The gap and the switching speed have a significant effect on the variation of the contact force.An increase in the switching speed during the reverse to forward switching process will result in an increase in the amplitude of the fluctuation.To prevent the mechanism from sticking,the baffle structure is optimized to eliminate the interference phenomenon,improve the overall reliability of the switching mechanism,and provide a theoretical basis for the design of the switching structure of marine gas turbines.
