Abstract

Hydraulic systems are crucial in ship and offshore engineering, where the severe marine environment demands excellent sealing performance. This study focused on the combined seals widely used in marine cranes, aiming to optimize their performance by applying the orthogonal design method. An elastohydrodynamic lubrication (EHL) model was employed for simulations and was subsequently validated using an experimental setup. The design of the simulation tests was meticulously planned using an

orthogonal table. The results including friction and leakage metrics for combined seals with varying structural and material parameters, were comprehensively analyzed. This analysis allowed for identifying key factors that significantly influence the seal's friction and leakage performance. Through optimization efforts, the friction of the combined seal is reduced to 90.63 %, while the leakage rate is simultaneously decreased to 87.43 %.

船用起重机液压组合密封的正交优化及参数分析

在船舶和海洋工程中，液压系统是至关重要的，在恶劣的海洋环境中需要优异的密封性能。以船舶起重机中广泛使用的组合密封为研究对象，采用正交设计方法对其性能进行优化。采用弹性流体动力润滑（EHL）模型进行了仿真，并通过实验装置进行了验证。采用L50（511）正交表对模拟试验的设计进行了精心规划。对不同结构参数和材料参数组合密封的摩擦和泄漏指标进行了综合分析。通过分析，可以确定影响密封摩擦和泄漏性能的关键因素。通过优化，组合密封的摩擦降低到90.63%，泄漏率同时降低到87.43%。
