Embodiment Construction

[0021] The structure and operation steps of the virtual assembly system based on the spacecraft assembly simulation technology described in the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Such as figure 1 As shown, the system can be divided into three modules, and two interface parts. With the support of Oracle database and CAD software (Pro / E), an object-oriented method is adopted to develop satellite virtual assembly process software. The architecture of the whole software is shown below.

[0023] (1) CAD modeling part: Parts and tooling tools are firstly designed in CAD software. By defining a series of mating constraints, these parts are assembled together to obtain the assembly model of the product.

[0024] (2) Process planning part: Firstly, a virtual assembly environment based on geometric constraints is established. Users perform interactive disassembly in this environment based on experience and knowle...

Abstract

The invention relates to a spacecraft assembly simulation technique-based virtual assembly system. The virtual assembly system comprises a CAD modeling module, a virtual assembly planning module and an assembly process design module, wherein the CAD modeling module is used for designing components and tooling tools, and assembling the components together by defining a series of matching constraint relations so as to obtain an assembling model of products; the virtual assembly planning module is used for establishing a geometrical constraint-based virtual environment, planning an optimized assembly sequence according to disassembly directions, disassembly tools and precedence constraint information recorded in the virtual environment for execution, verifying the optimized assembly sequence, and performing simulation evaluation in the virtual environment; and the assembly process design module is used for designing a product structure tree and a process step catalog, editing process steps and assembling a technological process. The CAD modeling module is connected with the virtual assembly planning module through a CAD modeling interface so that models generated in the CAD modeling module are guided into the virtual assembly planning module; and the process planning result in the virtual assembly planning module is guided into the assembly process design module through a Mockup interface.

Description

technical field [0001] The invention relates to a virtual assembly system and a virtual assembly method, in particular to a virtual assembly system and a virtual assembly method based on spacecraft assembly simulation technology. Background technique [0002] With the development of modern science and technology, the theories, methods and means of engineering design have undergone great changes. Especially in the past 30 years, the advanced level of engineering design methods and the degree of digitalization (CAD technology and FEA technology as a model) have largely determined the cycle, quality and cost of product design and development. CAD technology is the earliest and most successful model in computer application and engineering design. Its appearance and wide use have changed the traditional design method based on experience from the design method. The application of finite element analysis (FEA) technology in the engineering design process has once again greatly im...
