摘要：

通过动力学分析,确定水下滑翔机的体积变化范围达到±200 mL就可以保持滑翔运动.比较水下滑翔机经常采用的两类改变体积的方法,选用液压方式的浮力调节系统为水下滑翔机提供动力.浮力调节系统由外部油囊、内部油缸、双向泵、单向阀和电磁开关阀组成,采用AMESim软件的仿真分析结果表明,浮力调节系统工作时间稳定、排量变化均匀.实验结果表明,水下滑翔机的体积变化可以准确测量,集成于内部油缸的传感器使体积变化的分辨率达到0.76 mL,在0.2～1.5 MPa的环境压力下,浮力调节系统的排油和回油时间稳定在80 s左右,其工作性能符合水下滑翔机运动需求.
Abstract:

Dynamic analysis shows that an autonomous underwater glider can keep gliding as long as the range of volume changes up to ±200 mL. There are two kinds of methods to change the volume of the autonomous underwater glider. The autonomous underwater glider is driven by an electro-hydraulic buoyancy regulating system, which consisting of outer bladder, inner tank, two-way pump, one-way valve and electromagnetic switch valve. Simulation with the AMESim software indicated that the working time and the volume change rate of the buoyancy regulating system were kept well. The volume change of the autonomous underwater glider was measured accurately by the sensors built in the inner tank, and its resolution was 0.76 mL. The working time while oil drain and oil absorption approximates to 80s under the pressure from 0.2 MPa to 1.5 MPa. The dynamic performance of the buoyancy regulating system meets the demands of autonomous underwater glider．
