中文摘要:
      目的 提高海洋滑翔机浮力调节系统的可靠性,进一步降低系统功耗,设计气压与液压结合的低功耗浮力调节系统。方法 基于理论分析确定系统的体积控制量,设计气压调节模块以保证高压油泵的正常工作与回油的顺利进行。利用有限元方法分析承压管路的可靠性,通过实验测试,验证浮力系统的响应性能。结果 浮力系统的排油效率随着外压的增大而减小,2 MPa的压力会使出油率降低3%左右,同时功耗增加50%左右。在大气压力环境下,依靠系统内负压,400 s即可完成回油600 mL,完成上浮到下潜的转换。结论 设计的浮力调节系统的气压调节装置能以较低的功耗保障主泵的正常工作,同时保障回油过程的通畅,满足海洋滑翔机对浮力调节的要求,可以应用于一般海洋深度的水下滑翔机。
英文摘要:
      Objective To improve the reliability of the buoyancy regulating system of the underwater glider, further reduce the power consumption of the system, and design a low power consumption buoyancy regulating system combining air pressure and hydraulic pressure. Methods The volume of the system was obtained based on theoretical analysis. The air pressure regulating module was designed to ensure normal operation of the high-pressure oil main pump and keep the oil recovery smooth. The reliability of the pressure way was analyzed with the finite element method; and the response performance of the buoyancy system was verified through experimental test. Results The oil discharge efficiency of buoyancy system decreased with the increase of external pressure. The pressure of 2Mpa would reduce the flow rate about 3% and increased the power consumption by about 50%. Under the barometric pressure, based on the negative pressure in the system, the system drained back 600mL of oil within 400s. The conversion of floating and diving was completed. Conclusion The air pressure regulating device designed for the buoyancy regulating system guarantees normal working of the main pump with lower power consumption and smooth oil return of the system. The designed buoyancy system fits the requirements of the underwater glider, can be applied to the underwater glider working in the general ocean depth.
