Design and Implementation of Mass Property Management System for Aerospace Vehicle

质量特性作为空天飞行器总体设计的关键控制参数,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;基于数字化设计环境和飞行器数字样机,提出了全飞行器质量特性管理系统方案,并在此基础上开发了原型系统,对设计思路进行了验证;相比于传统质量特性的计算及管理方法,该系统可有效提高设计效率,实现飞行器质量特性全寿命周期的动态可控、可见和可追溯;该成果后续还可推广应用于其他航天器研制。

The mass property is a key important control parameter which associated with overall performance and key technical index of aerospace vehicle, the design and control of mass property is important in the development of aerospace vehicle. The management system of mass property is presented in this paper, the proposed design of system was validated by prototype system on a basis of digital mock-up in digital environment. The dynamic controllability, visibility and traceability of the change process of mass property are realized by the system, which has faster computing speed and higher data accuracy compared to the traditional mass property of the calculation and management method.
