| Abstract: | The temperature field mode of the orientation case for a type of liquid floated gyro is introduced. Based on this modal, the equivalent temperature field is analyzed with ANSYS. A finite element simulation software and an accurate distribution are obtained. The initial heat source for the inertial system is found according to the accurate value. Meanwhile, the correctness of the result that gained by the analysis is confirmed with experiments. Much important reference data are obtained which can be used in the coming research. |
