摘要
摆式积分陀螺加速度计(简称陀螺加速度计)具有高精度、大量程、抗干扰、能自动积分等优点,广泛应用于国内外远程火箭的高精度惯性导航与制导系统中。通过采用动压气浮、全液浮、磁悬浮支承技术,三浮陀螺加速度计成为目前工程应用中最高精度的加速度计。综述了三浮陀螺加速度计的发展现状、技术优势及其三浮支承、伺服控制和精密制造等关键技术,并对陀螺加速度计的技术发展进行了分析。
Pendulous integrating gyro accelerometer(PIGA)is widely used in high-precision inertial navigation and guidance systems for long-range rockets at home and abroad because of its high-precision,large range,anti-interference and automatic integration.By adopting air-flotation,liquid-floating,and magnetic levitation support technology,the tri-floated PIGA has become the most accurate accelerometer in current engineering applications.The current development status,technological advantages,key technologies such as tri-floated support,servo control and precision manufacturing of tri-floated gyroscope accelerometers are summarized.Finally,the development of the PIGA technology is prospected.
