空间站舱外设备视场动态仿真方法

A method for dynamic simulation of view-field of space station extravehicular equipment

针对空间站多构型、多任务、多运动部件的特点,提出舱外设备视场动态仿真分析需求。基于数字空间站孪生平台,采用虚拟现实技术,对舱外设备视场遮挡动态仿真方法进行研究。设计了一套通用的可视化系统,搭建了整体轻量化可视模型,涵盖太空环境、舱外运动部件和舱外敏感器的轻量化显示,并加入了视场遮挡、中继星跟踪等量化后处理功能和敏感器(天线)的有效视场分析功能,以支撑空间站飞行任务规划和飞行程序推演过程中的动态仿真验证。该方法已在空间站在轨飞行任务设计过程中得到实际应用。

Aiming at the space station with multi-configuration,multi-task and multi-moving parts,a dynamic simulation requirement for the view-field of extravehicular equipment was proposed.Based on the digital twin platform of space station and by using VR technology,the method for dynamic simulation of viewfield of space station extravehicular equipment was studied.A universal visualization system was designed,and a lightweight visualization model including lightweight display of space environment,extracurricular moving parts and extracurricular sensors was built.The quantitative post-processing of view-field occlusion and relay satellite tracking,as well as the effective analysis of view-field of the sensor(antenna) were added to support the dynamic simulation verification of space station mission planning and flight program deduction.This method has been applied in the design of space station mission in orbit.
