摘要
针对二位置、四位置光纤陀螺仪寻北仪齿轮啮合时配合间隙而无法实现高精度方位测量的问题,设计新的V型槽定位方式,并介绍关键结构的设计方案:转位结构体组件、限位驱动组件、转位驱动组件,推导光纤陀螺仪寻北仪在水平和倾角状态下的方位角解算公式;为确定所设计光纤陀螺仪寻北仪的抗振动性能,进行仿真分析。仿真结果表明:安全系数和最大变形量均满足工程要求;通过实验测得了寻北仪横滚角、俯仰角和方位角测试精度以及横滚角、俯仰角和方位角重复性精度。
In order to solve the problem that high precision azimuth measurement can not be realized due to the fit clearance when the gears of two-position and four-position fiber optic gyroscope(fog)north finders are engaged,a new V-shaped groove positioning mode is designed,and the design scheme of the key structures is introduced,including the transposition structure assembly,the limit drive assembly and the transposition drive assembly,and the azimuth calculation formula of the fog north finder in the state of level and inclination is derived;In order to determine the anti-vibration performance of the designed fiber optic gyroscope north finder,the simulation analysis is carried out.The simulation results show that the safety factor and the maximum deformation meet the engineering requirements.The test accuracy of roll angle,pitch angle and azimuth angle and the repeatability accuracy of roll angle,pitch angle and azimuth angle of the north finder are measured by experiments.
