Lightweight modeling method of satellite cable

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.
