Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and an example of an MBD model of a cable assembly of an electromechanical product.

[0041] like Figure 1-10 .

[0042] An MBD model of a cable assembly constructed according to the characteristics of the cable assembly is as follows: figure 1 As shown, it consists of coordinate system, geometric information, topological information, electrical information, labeling set and other information. Among them, the labeling set includes geometric dimensions, part properties, electrical connection relations, material details and so on. Among them, the coordinate system is the coordinate system of each part that makes up the cable assembly; the geometric information is the geometric model, geometric size and tolerance of each part; the topological information is the relationship between the cable branches and the relationship between the cable and other parts The electrical in...

Abstract

An MBD model of a cable assembly and an automatic generation method thereof are characterized in that the MBD model of the cable assembly is constructed according to the characteristics of the cable assembly, other information is organized and stored based on topological information of the cable assembly, an MBD information model of the cable assembly is formed, and after a cable layout result XML file is read, automatic cable modeling is carried out by means of a secondary development interface of CAD; then, based on the MBD information model, labeling information and labeling objects of the parts are obtained, thus automatically performing three-dimensional labeling of the information, and completing automatic generation of the MBD model of the cable assembly. According to the computer-aided design method for the MBD model of the cable assembly, design modeling of the cable assembly is automatically carried out in a full-three-dimensional environment, the product design efficiency can be effectively improved, and the research and development period of products is shortened. Particularly, the problem that the MBD model of the cable assembly in a product digital prototype based on model definition is difficult to design is solved.

Description

technical field [0001] The invention belongs to the field of computer-aided design, in particular, it organizes various information of cable assemblies based on topological information and stores them in the computer memory, and then obtains the content of the label set of each part according to the definition of the label set to realize the information A method for automatic three-dimensional labeling, specifically an MBD model of a cable assembly and an automatic modeling method thereof. Background technique [0002] As an important part of electromechanical products, cables are mainly used for the transmission of electric energy or signals, and are widely used in complex electromechanical products such as aerospace, ships, and vehicles. With the development of mechatronics technology, the number of cables used in electromechanical products is also increasing. The cables in the same area or responsible for the same functional module will be bundled, and then connectors wil...
