摘　　要：为提高大型游乐设施的安全性和可靠性,非均匀负载工况下液压提升系统双液压缸不同步的问题需要得到解决。以6人舱青蛙跳液压提升系统为研究对象,提出基于分流集流阀的同步方案,并根据液压提升系统的运行原理及其主要部件的性能参数,建立AMESim模型仿真分析。仿真分析表明,该同步方案能够在不影响系统稳定时间、不增加系统复杂度的前提下,显著改善液压缸的同步性能,将两侧液压缸运行速度同步误差控制在0.4%,活塞杆满行程时两侧液压缸相对位移约为0.019 m,完全满足安全运行的需要。In order to improve the safety and reliability of large-scale recreation facilities, it is necessary to solve the problem of non-synchronization of double hydraulic cylinders under non-uniform load conditions. We take a 6-person cabin frog jumping hydraulic lifting system as the research object. A synchronization scheme based on split manifold is proposed. And then, based on the operating principle of the system and the performance parameters of the main components, a model simulation analysis is established by employing AMESim software. The simulation results show that the synchronization scheme can remarkably improve the synchronization performance of the hydraulic cylinders without affecting system stability time and increasing system complexity. The synchronization error of the running speed of the hydraulic cylinders on both sides can be kept at 0.4%. Besides, the relative displacement of the hydraulic cylinders on both sides is about 0.019 m,when the piston rod is full stroke. These results fully meet the requirements of safe operation.
