设计一种基于蓄能器和液压缸的被动式船舶吊机升沉补偿系统，为了提高系统补偿率，对其进行动力学分析和性能指标分析，提出一种基于节流阀的改进方案，即在液压管路中加入节流阀，通过改变节流阀通径和个数，调整系统阻尼比至合适值，从而提高系统补偿率。改进前后的系统仿真对比结果表明：基于节流阀改进方案的被动式升沉补偿系统具有更好的补偿效果。
設計一種基于蓄能器和液壓缸的被動式船舶弔機升沉補償繫統，為瞭提高繫統補償率，對其進行動力學分析和性能指標分析，提齣一種基于節流閥的改進方案，即在液壓管路中加入節流閥，通過改變節流閥通徑和箇數，調整繫統阻尼比至閤適值，從而提高繫統補償率。改進前後的繫統倣真對比結果錶明：基于節流閥改進方案的被動式升沉補償繫統具有更好的補償效果。

A passive heave compensation based on the hydraulic accumulator and hydraulic cylinder is designed .For in-creasing the compensation rate , the dynamic analysis and performance analysis are conducted .An improvement based on throttle valve is put forward , which means adding throttles valve in the hydraulic pipeline .The diameter and amount of throttles can be changed to adjust the damping ratio to appropriate value , thus increasing the compensation rate .The simulations of the system before and after improvement are conducted and the result indicates that the system after improvement has better compensation effect.
