摘要
Abstract
To solve the problems of poor response speed,insufficient dynamic positional stiffness,and low system stability in mechanical hydraulic servo devices for marine controllable pitch propellers,a mathematical model of the servo device is established.The analysis identifies the factors affecting its performance as the geometry and number of throttle grooves,main control valve's underlap and hydraulic cylinder's diameter.Based on the AMESim simulation platform,the quantitative relationships between these parameters and performance indicators are systematically investigated.The results show that K-shaped throttle grooves exhibit superior performance in both response speed and dynamic positional stiffness compared with other groove configurations.Increasing the number of throttle grooves enhances response speed and dynamic positional stiffness but degrades system stability.A larger underlap of valve improves response speed but reduces dynamic positional stiffness.Enlarging the diameter of hydraulic cylinder sacrifices response speed but improves dynamic positional stiffness and system stability.Based on a comprehensive comparison of the optimization effects brought about by different degrees of changes in influencing factors and the adaptability under different working conditions,an optimization plan is finally proposed:A combined design of six circumferentially arranged K-shaped throttle grooves with a 0.6 mm underlap and a 600 mm cylinder diameter is adopted.The verification demonstrates that the optimized device achieves a 3.94％reduction in response time,a 1.28％increase in dynamic positional stiffness and significant overall performance improvement while maintaining system stability.The research results provide an important theoretical basis for the performance optimization of hydraulic servo devices for marine controllable pitch propellers.关键词
