摘　　要：升船机的船厢门锁定机构液压系统部件内泄漏是影响船厢门性能和可靠性的主要故障形式。文章选取了船厢门锁定机构的锁定油缸和电磁换向阀作为研究对象,分析了内泄漏问题的故障机理,并在AMESim软件平台上分别搭建了锁定油缸和电磁换向阀的内泄漏仿真模型。分别计算了锁定油缸和电磁换向阀的间隙量、偏心距和油液动力黏度等不同参数对内泄漏量的影响,得到了锁定油缸内泄漏量和电磁换向阀内泄漏量随时间的变化曲线。仿真结果表明,间隙量对内泄漏量的影响最大,及时换新液压油,保证安装精度可以有效减小内泄漏量。The internal leakage of the hydraulic system components of the cabin door locking mechanism of a ship lift is the central failure mode affecting the performance and reliability of the cabin door.This paper selects the locking cylinder and the electromagnetic directional valve of the locking mechanism for the cabin door as the research objects,and the failure mechanism of the internal leakage is analyzed.In addition,the internal leakage simulation models of the locking cylinder and the electromagnetic directional valve are respectively built on the AMESim soft⁃ware platform.The influence of different parameters such as clearanc,eeccentricity,and oil dynamic viscosity of the locking cylinder and the electromagnetic directional valve on the internal leakage is calculatedand the change curves of the internal leakage of the locking cylinder and the electromagnetic directional valve with time are obtained.The simulation results show that the clearance imposes the greatest impact on the internal leakageand the internal leakage can be effectively reduced by timely replacing the hydraulic oil to ensure installation accuracy.
