Flexible cable process digital prototype construction system and method for spacecraft assembly

Abstract

The invention discloses a flexible cable process digital prototype automatic construction system for spacecraft assembly. The flexible cable process digital prototype automatic construction system mainly comprises the following modules: an interface module, a product classification module, a connection relationship identification module, an assembly relationship resolving module and a cable process digital prototype construction module. According to the invention, rapid construction of the flexible cable process digital prototype is realized, and related requirements of cable laying are met; on the basis of simplifying an overall unit cable design model, complete information required by cable laying is reserved, and the probability of quality occurrence in the cable laying process in narrow spaces such as satellites is reduced.

Description

technical field [0001] The invention belongs to the technical field of spacecraft general assembly, and in particular relates to a system and method for automatically constructing a digital prototype of a flexible cable process oriented to spacecraft general assembly. Background technique [0002] At present, the design work of my country's satellites and other spacecraft products has been widely realized in 3D, and various design information is transmitted in the form of 3D models combined with external controlled technical documents. Based on the 3D design model of the overall unit, the final assembly department built a digital prototype of the general assembly process through lightweight processing and BOM (Bill Of Material) reconstruction (such as adding tooling tools, process protection parts, assembly relationship reconstruction, etc.), and realized Material matching and convenient application of stand-alone equipment. However, for the laying and assembly of flexible ...

Problems solved by technology

[0003] 1) The branching relationship of the cable assembly is complex. Generally, one cable is connected to multiple stand-alone devices. However, all cables are displayed synchronously in the cable design model, and the final assembly implementation needs to be laid one by one. Find the information of the laid cables (such as connected products, direction, products to be avoided, etc.);

[0004] 2) Due to the extremely narrow assembly space of satellites and other spacecraft, if the cables cannot avoid related products or do not reserve a safety gap when laying cables, it may cause quality problems such as cable damage;
