Influence of Temperature and Pressure on Nozzle Array Fluidic Gyroscope

Abstract:

In this paper, the temperature and pressure distribution in sensitive element of nozzle array structure gyroscope is analyzed. Using ANSYS-FLOTRAN CFD software, the finite element simulation is conducted by a series of procedures, such as two-dimensional model building of fluidic gyroscope, mesh, load applying and equation solving. The temperature and pressure distributions of nozzle array structure fluidic gyroscopes are calculated. The results show that the thermal wires heat temperature of the surrounding gas which place at 1.5mm from the outlet, and which produce internal temperature gradient in sensitive cavity, temperature changes symmetry of the cavity center. The pressure near the outlet is higher than any other position in the cavity, and which is 0.21109Pa. In this paper, the structure optimization of nozzle array gyroscope which provides effective theoretical basis for improving its performance.
