摘要: 为了探索模块化航天器的分析问题,基于航天器结构的模块化设计概念,建立了一种支持在轨展开的航天器模块化构型,并基于虚拟样机技术,对其在空间失重状态下,太阳帆板和模块化本体同时展开对航天器姿态的影响进行仿真,发现本体各模块的展开对航天器姿态角和姿态角速度影响起决定性作用;以Eclipse为开发环境,基于J2EE技术开发了航天器结构设计分析平台,将航天器结构设计、装配和动力学分析集成在一起,以实现航天器从模块化结构设计、数字样机装配到力学分析的快速响应。Abstract: In order to explore the analysis methods of modular spacecraft,based on the concept of modular design for spacecraft structure,a deployable on-orbit spacecraft modular configuration was established.The influence of simultaneously deployment solar panel and modular structures under the circumstance of weightlessness on the spacecraft's gesture was simulated and analyzed with the assistance of virtual prototype technology.The simulated results show that the deployment of module structures is vital to the angle and velocity of spacecraft's gesture.Within the Eclipse environment,a structural design and analysis platform for spacecraft was developed with J2EE.The structure design,assembly and dynamics analysis of spacecraft were well integrated,and the rapid response of structural design and digital prototype assembly to dynamics analysis of spacecraft was consequently achieved in this simulation platform.
