Research and Implementation of layoutLayout rapid Rapid design system for Aerospace Vehicle

摘要:

飞行器总体布局设计作为空天飞行器总体设计的核心工作之一，与飞行器总体性能和技术指标密切相关，其设计与控制贯穿空天飞行器研制全过程。基于空天飞行器总体布局“五约束”、“六要求”、“十流程”，提出了空天飞行器总体布局快速设计系统方案，并基于CATIA VPM数字化设计环境开发了原型系统。工程实践结果表明，文章提出的系统方案解决了飞行器外形、结构布置、系统布置和质量特性快速精细化设计及总体布局设计难以自动调整、快速迭代优化的难题，实现了飞行器外形、结构布置、仪器设备的参数化、实体化、具体化、可视化及质量特性动态分析与评估。该成果后续还可推广应用于其他航天器研制。

Abstract:

The layout design is a key important work in the development of aerospace vehicle which associated with overall performance and key technical index of aerospace vehicle. Base on “five constraints”, “six requirements”, “ten process” of layout for aerospace vehicle , the system for layout rapid design is presented, which was validated by prototype system on a basis of CATIA VPM in digital environment. The engineering practice shows that the system could resolve problems of detailed design of outline , structure layout, instrument layout, mass property analysis and automatic adjustment and rapid integrated optimization for outline design during layout design, and realized the parametric design, materialization and visualization of outline, layout , equipment and mass property ,and dynamic analysis and evaluation of layout. This system can be used as reference for the layout design of other spacecraft.
