文章分析了地面重力环境和在轨内压环境对不同位置和状态下的载人航天器陀螺组件及姿轨控敏感器设备安装精度的影响,并进行了试验验证,分析结果与试验数据一致性较好。研究结果显示:设备布局位置不同,其安装精度受环境差异的影响程度也不同;航天器在空载、垂直停放状态下,设备安装精度受地面重力环境影响较小;陀螺组件和姿轨控敏感器A的安装精度受在轨内压环境影响较小,在地面常压环境下的精测结果能够真实反映其在轨状态,而姿轨控敏感器B的安装精度受压力环境影响明显。以上结果可为航天器设备布局及精度测量工作提供借鉴。
The paper analyzes the influence of the gravitation environment and in-orbit pressure environment on the installation accuracy of the gyro components and attitude-rail-controlled sensors in different positions and states, and verifies the results. The analysis results agree well with the experimental data better. The research results show that the installation accuracy of the spacecraft is different from that of the environment due to the different locations of the equipment layout. The accuracy of the equipment installation is less affected by the gravitation environment under no-load and vertical parking conditions. The mounting accuracy of device A is less affected by the in-rail pressure environment. The results of fine measurement under the normal atmospheric pressure in the ground can truly reflect the on-orbit state, while the mounting accuracy of the position-and-attitude control sensor B is significantly affected by the pressure environment. The above results can provide reference for spacecraft equipment layout and accuracy measurement.
