Study of the impact resistance of a self-balancing resistive thermal expanding flow gyroscope

We propose thermal expansion flow gyroscopes with self-balancing resistance and study their impact resistance. In this paper, a thermal expansion flow gyro with self-balancing resistors is used as the research basis, aiming to improve the environmental adaptability of the gyro through technological innovation. The thermal expansion flow gyro contains an upper chamber, a lower chamber and a base layer, which contains four thermistors, two heating resistors and two balancing resistors. In order to improve the detection accuracy of the Wheatstone bridge, the balancing resistors and thermistors are fabricated using the same MEMS process, which ensures that the balancing resistors are highly consistent with the thermistors in terms of material, structure, and process, and achieves a high degree of matching and stability. Based on the above analysis, we carried out a finite element analysis of the impact resistance of the self-contained balancing resistor thermal expansion flow gyro. The experimental results show that the impact resistance of this thermal expansion flow gyro can reach 14,752 g when the load is applied in 0~10ms, which fully proves its high stability in harsh environments. The results of this study will provide a reference for subsequent gyro performance studies.
