摘要

摘要: 依据垂直微结构剖面仪工作原理，探讨了垂直微结构剖面仪测量过程中对于下降速度的要求，确定了其下降速度范围。分析了影响垂直微结构剖面仪下降速度的因素，提出了垂直剖面仪下降速度控制的方法：可通过调节垂直剖面仪下降过程中的水阻力来实现对下降速度的控制。对于下降过程中剖面仪所受的水阻力，采用基于动网格技术的流固耦合数值仿真方法，计算了带有弹性阻尼刷的垂直微结构剖面仪的阻力系数，并通过海试试验验证了计算结果的准确性。

Abstract: Based on operating principles of the vertical microstructure profiler (VMP), requirements for its sinking velocity were discussed and the range of its sinking velocity was determined. After analyzing the factors that affect the sinking velocity, the method for controlling it was presented namely adjusting the hydraulic drag during the profiler's free-falling. Based on dynamic mesh, the fluid-structure coupling was calculated with the ANSYS-CFX codes to solve the hydraulic drag of the VMP with elastic drag whiskers. The calculation accuracy was verified by sea tests.
