摘　　要：浮标的续航能力是影响到浮标整体性能的重要指标之一,在浮标工作过程中耗能最大的部分是浮力调节系统主动调节的过程。基于对浮标运动特性以及耗能原因的分析,提出上浮阶段过程中采用分段排油策略的方案,减少浮力调节过程中排油所需要消耗的能量。通过构建浮标的运动模型和耗能模型,在理论推导和计算基础上,分析得到速度区间设置和分段排油次数对浮标上浮运动过程耗能的影响关系,结合实例验证分段排油策略可以有效减少浮标上浮阶段的耗能。The endurance of the float is one of the important indicators affecting the performance,and the most energyconsuming part of the overall operation is the process of starting the buoyancy regulation system for oil discharge.Based on the analysis of motion characteristics and energy consumption reasons,a scheme of multi-step buoyancy regulation strategy to save energy in the process of floating is proposed.The motion model and energy consumption model are constructed,and the relationship between the speed interval setting and the number of oil discharges on the energy consumption of the floating motion process is theoretically analyzed.The feasibility of the segmental oil discharge strategy and the energy saving effect are verified in the example.
