Description

Technical Field

[0001] The present invention relates to the field of rocket and satellite fairing assembly, and in particular to an assembly device and a processing method for an oversized composite material semi-shell structure. Background Art

[0002] The 5200 rocket's satellite fairing barrel has a diameter of 5.2 meters, making it the largest composite satellite fairing in China. Its von Karman section and barrel are composed of a composite skin surrounded by metal profiles. The sections are then docked together to form the satellite fairing. The poor overall stiffness and easy deformation of the pre-segmented fairing create significant difficulties during assembly. Assembly accuracy also affects fairing separation, ultimately impacting the success of the rocket launch.

[0003] In the past, satellite fairing shells were relatively small, and assembly was performed while they were lying flat on the ground. However, if the 5200 satellite fairing shell were assembled while lying flat on the ground, the shell would be too large, and gravity would cause deformation. Therefore, an assembly device was invented that allows the fairing shell to be assembled while lying flat on the ground. While lying flat on the ground, the shell has a support structure that effectively reduces deformation and allows for docking between shell segments, ensuring assembly accuracy.
