【摘要】：由于航天工业领域对数字样机的定义和认识不统一,造成的数字样机技术应用推广进展缓慢、不同单位对数字样机的管理方法和水平参差不齐、基于数字样机的跨单位协同研制工作开展困难等问题。以航天运载器产品为对象,结合产品研制现状及系统工程模式,从产品研制进程和数字样机应用目的两个维度,提出一种航天产品数字样机的定义和分类方案。以运载器产品研制进程为主线,将数字样机定义为一级、二级、三级和四级样机,按照应用目的的区别,将研制数字样机分为功能、性能和构造样机,一方面规范航天产品数字样机技术状态管理,另外可提高数字样机产品的研制水平。
[Abstract]:Because the definition and understanding of digital prototyping in aerospace industry are not uniform, the application and popularization of digital prototyping technology is slow, and the management methods and levels of digital prototyping in different units are not uniform. It is difficult to carry out collaborative development of cross-unit based on digital prototype. Taking the spaceflight launch vehicle product as the object, combining the current situation of the product development and the system engineering model, this paper puts forward a definition and classification scheme of the digital prototype of the aerospace product from the two dimensions of the product development process and the purpose of the application of the digital prototype. Based on the development process of launch vehicle products, the digital prototype is defined as the first, second, third and fourth class prototypes. According to the difference of the purpose of application, the digital prototype is divided into function, performance and construction prototype. On the one hand, the state management of digital prototyping for aerospace products can be standardized, and the development level of digital prototyping products can be improved.
