Design and Experiments of Shear Probe for Ocean Turbulence

Shear probe is an important instrument to measure ocean microstructural turbulence. The structure,the assembly and the signal processing of shear probe have great influence on its accuracy. In this paper,Fluent was used to analyze hydrodynamic capability for shear probe shell and ANSYS was used to compute deformation and charge produced by the inner structure of shear probe so that shell and inner structure can be improved according to the computation. Special clamp was devised to assemble shear probe accurately.so as to achieve the precision about 0.01 mm. In order to process the signal of shear probe and to calibrate its sensitivity ,data acquisition system with low power and high precision was developed based on MSC1210 and LPC2114 microprocessor,and calibration mechanism was designed to test and calibrate shear probe. Experiments show shear probe and data acquisition designed in this paper can satisfy the requirement of ocean turbulence.
