为了掌握加速度计内部温度场规律,得到内部的实时温度,建立石英挠性加速度计的热仿真模型,进行热仿真分析。根据仿真模型设计温度试验,验证了模型的正确性。在加速度计稳定状态下,仿真温度值与试验值差0.2℃左右;根据试验结果对仿真结果进行修正,将修正后的仿真结果与试验结果进行比较,得到两者的差值为-0.011℃,有效地提高了仿真结果的准确性。因此,可以通过修正仿真结果得到加速度计内部的实时温度。
In order to grasp the internal temperature field of the accelerometer and get the real-time temperature inside, the thermal simulation model of the quartz flexible accelerometer is established and the thermal simulation is carried out. According to the simulation model design temperature test, the correctness of the model is verified. When the accelerometer is in steady state, the simulation temperature is about 0.2 ℃ lower than the experimental value. According to the test results, the simulation results are corrected. The corrected simulation results are compared with the test results, the difference between them is -0.011 ℃, Effectively improve the accuracy of simulation results. Therefore, the real-time temperature inside the accelerometer can be obtained by correcting the simulation results.
