摘要
半球谐振陀螺仪(HRG)是一种高精度、高可靠、长寿命的新型固体振动陀螺仪,在宇航领域有广泛的应用前景.分析了影响半球谐振陀螺工作寿命的主要因素,采取措施以提高陀螺工作寿命,并持续开展陀螺寿命试验,验证了半球谐振陀螺主要指标的长期性能.结果表明,半球谐振陀螺在长期通电工作过程中,性能稳定,工作寿命可达20年,满足深空探测器等执行长期空间任务的应用需求.
Abstract
The hemispherical resonator gyro(HRG)is a new solid state vibrating gyro that offers high preci-sion,high reliability,and a long life.It has broad application prospects in the aerospace field.This study analyzes the main factors affecting the working life of the HRG,proposes measures to improve the working life of gyro-scopes,conducts long-term continuous gyroscope life tests,and verifies the long-term performance of the main indi-cators of the HRG.The results show that the HRG has a stable performance and a working life of as many as 20 years during long-term electrification,thus meeting the application requirements of long-term space missions,such as deep-space detectors.
