摘　　要：以双驳船同步提升技术为研究对象,分析了该技术在海上打捞工程中的重要意义,同时提出了该技术存在的不足;为了提高同步提升的适应性及效率,提出了一种主动补偿策略;为了研究该策略的可行性,搭建了模拟沉船同步提升的液压升沉补偿试验平台,针对其中的六自由度升沉补偿试验台的设计,对其进行了力学分析,得到了沉船负载的加载力与六自由度平台的6个液压缸的驱动力之间的关系,为负载的选取与液压缸额定载荷的设计提供理论依据。利用ADAMS和MATLAB联合仿真,验证了试验台运动的可模拟性和主动补偿策略的可行性,为进一步研究沉船同步提升过程中升沉补偿控制策略提供了数据支持和理论依据。The synchronous lifting technology of double barges was taken as the object of study. The importance of this technology in the salvage industry was analyzed, and its some shortages were put forward. In order to improve the efficiency and adaptability of synchronous lifting, an active compensation strategy was proposed. In order to study the feasibility of the strategy, a hydraulic heave compensation test platform was built to simulate the synchronous lifting of the wreck. Aiming at the design of the six degree of freedom （6D） heave compensation test platform, the mechanical analysis was carried out, and the relationship between the loading force of the ship load and the driving force of the six hydraulic cylinders of the platform with 6D was obtained. It could provide theoretical basis for the selection of load and the design of rated load of hydraulic cylinder. The feasibility of the control model and the feasibility of the active compensation strategy are verified by the co-simulation of ADAMS and MATLAB. It provides data support and theoretical basis for the further study of the heave compensation control strategy during the double barge synchronous lifting.
