Modeling and Simulation of Hydraulic Clamping System of Tensioner for Deep Water Pipelaying Vessel

综合考虑3000m水深铺管船用张紧器的工作过程及参数要求,设计液压夹紧系统为管线提供夹紧力并确定液压系统元件参数。利用AMESim软件建立仿真模型,并对液压缸快进、工进、保压、快退四个工作阶段及同步性进行仿真分析,除快进阶段液压缸存在速度波动外,其余三个阶段运行平稳;采用PID控制使液压缸具有良好的同步性,并通过分析液压缸动态特性,对液压系统进行优化。仿真结果表明液压夹紧系统基本满足张紧器工作要求。

With integrated consideration of working process and parameters of tensioner for pipelaying vessel with the water being 3000meters deep, a hydraulic clamping system was designed to clamp pipe, and its components parameters were obtained. The simulating model was created based on AMESim software, then the corresponding simulation of hydraulic cylinder on the stage of fast-forward press pressure maintaining quick return and synchronism was shown, besides the speed fluctuation during the stage of fast-forward, the other three stages were steady, and using PID control, the hydraulic cylinders have good synchronism. According to analysis the Dynamic dynamic characteristics of hydraulic cylinder, hydraulic system was optimized. The results show that the hydraulic clamping system meets the requirements of tensioner.
