Lightweight modeling method of satellite cable

Abstract

The invention discloses a lightweight modeling method of a satellite cable. Based on the computerized design technique and the Pro / E secondary development technology, the lightweight modeling method comprises the steps of 1, establishing a three-dimensional electrical connector lightweight model in Pro / E, 2, establishing a cable joint table in a computer system, 3, generating a lightweight cable joint table by use of a Pro / E secondary development tool, 4, designing a cable trend path in the Pro / E, 5, reading in the lightweight cable joint table in the Pro / E and creating a three-dimensional cable lightweight model, 6, performing model examination in the Pro / E, and 7, assembling the cable model and the electrical connector model in the Pro / E. The lightweight modeling method of the satellite cable has the advantages that the size of a three-dimensional cable model file can be greatly reduced, the three-dimensional modeling of the satellite cable can be improved, the length and the weight of the cable can be accurately controlled and the efficiency and the quality of the satellite cable design can be improved, based on the lightweight thought and by maintaining the major information of cable modeling and neglecting secondary and irrelevant information.

Description

technical field [0001] The invention belongs to the technical field of digital design of spacecraft cable networks, and in particular relates to a lightweight modeling method for satellite cables. Background technique [0002] With the development of CAD technology, 3D modeling has been maturely applied in various industries and fields. In the field of aerospace, especially in the design of many subsystems of satellites, 3D modeling methods have been widely used. However, for the cable network, due to its special features such as complex contact information and a large number of contacts, cable modeling requires very high computer hardware resources, and there are some difficulties in directly using Pro / E for 3D modeling of satellite cables. [0003] As satellite functions and structures become more and more complex, the number of cables involved is also increasing, and more stringent requirements are placed on the length and weight of cables. Therefore, it is necessary to...
