Transducer Calibration

The actual use conditions of force transducer is differences between the factory verification conditions, so based on the structure and working principles, this article is aimed at accurate calibration and proper use of force transducer. Through the CAE simulations and calibration experiments in actual working conditions which are the installation pre-tightening force, structure of fittings and pedestal’s hardness, analyses the output signals of force transducer. Force standard machine was carried out on the calibration experiment to verify the correctness of the numerical simulation. And then the outcomes obtained by numerical simulations and the calibration experiments, it studies the differences of every output performance index of force transducers in different working conditions above-mentioned.

Simulation models based on the different structural levitation vortexes were built, the analysis on the flow characteristics of pressure distribution and bearing capacity was conducted by using the RNG κ-ε turbulent model and non-uniform meshing in variable working conditions. At last, the influence factors and variation rules of vortex adsorption negative pressure effect were obtained. The theory and the experiment results indicate that the vortex carrier with symmetrical tangential air supply has the optimal stability, but the optimal negative pressure effect and the great lifting force are obtained by the vortex carrier with tangential single air supply.

An integral FEA model and a nonlinear contact algorithm were emplyed for the double-cone seal structure, which were applied on the large-sized double-cone seal structure under internal pressure. The stress distribution of double-cone ring and gasket under pre-tightening and working conditions, as well as the influence of pre-tightening force and internal pressure on the gasket stress, double-cone ring strain and radial clearance, were obtained. If the radial clearance was designed according to g⩾0.1% D1, the material of double-cone ring would yield globally. Meanwhile, If the radial clearance was designed according to g⩽0.05%D1, the sealing performance in the pressurizing process would not be ensured. A radial clearance g=(0.075%∼0.1%)D1 is recommended.

Based on the principle of fiber-optic gyro inclinometer, the characteristics of horizontal freezing hole and the working conditions, it is analyzed that the horizontal hole fiber-optic gyroscope tilting technology for freezing holes is one of the most reliable methods. In order to verify the azimuth measurement error of the horizontal fiber optic-gyro inclinometer, the simulation test under the 1:1 working condition was carried out with the actual working conditions on site. Compared with the total station measurement data, it was concluded that 85.2% of the data is in measurement error within ±2°, 55.6% of the data is within ±1°, which verifies the reliability of the measurement data of the horizontal fiber-optic gyro inclinometer. At the test level of α=0.05, the azimuth test error accords with the normal distribution of μ=0.54 and σ=0.73. In the actual use process, the algorithm can be used to optimize the measurement data by taking multiple measurements and taking the average value in combination with the field conditions, so that the data can be closer to the true value.
