| 摘 要： | 液浮惯性仪表精度跟温度场有关联，温度分布不均匀和温度波动都会对仪表精度产生影响，因此研究液浮惯性仪表内部的温度场分布尤为重要。利用有限元方法对液浮惯性仪表进行温度场仿真计算，根据仪表的结构特点合理的设置了测温点，通过试验的方法提取了特征点的温度值，验证了仿真结果的正确性，为液浮惯性仪表的热设计提供了基础参数。

| Abstract: | The precision of liquid floated inertial instrument(LFII) is influenced by temperature. Uneven distribution and fluctuation of temperature field could decrease the precision of LFII. It''s very important to analyze temperature field distribution in LFII. With finite element method, temperature simulation and analysis for LFII was presented. According to structural features of the instrument, temperature testing points were set rationally. It was shown that the result of simulation coincided well with the experiment data. It benefits the thermal design for LFII. |
