Abstract

Abstract

In order to study the influences of the heating mechanism on the vapor cell of the nuclear magnetic resonance gyroscope(NMRG), several different heating methods are designed to heat the vapor cell. The finite element analysis software ANSYS is used to establish a temperature field model of the vapor cell, afterwards the model is simplified and finally the steady-state temperature field of the surface is given. Meanwhile, a temperature measurement circuit with the precision of 0.01℃ is made to detect the temperature of different places on the surface of the vapor cell, thus getting the changes of the surface temperature of different methods. The experimental results are compared with the simulation results, and the calculation error turns out to be less than 5%, which verifies the validity of the temperature model. Based on both of the experimental and simulation results, and after comparison of temperature field of the vapor cell surface through different heating methods, the best heating method is given, which can makes the most uniform temperature field of the vapor cell surface.
