High-precision cabin connection method suitable for whole-satellite micro-vibration test

Abstract

The present invention discloses a high-precision cabin segment connection method suitable for whole-satellite micro-vibration tests, and belongs to the field of spacecraft test technology. The method first roughly adjusts the lateral and longitudinal relative deviations of the upper cabin segment relative to the flexible connection device, and then precisely adjusts the longitudinal position and posture of the upper cabin segment relative to the flexible connection device; then, by operating the adjustment device, the X and Y distance deviations of the connection points on the adjustment device relative to the connection points of the flexible connection device meet the docking requirements; then confirm whether the lateral docking accuracy of the upper cabin segment relative to the flexible connection device meets the docking requirements, and finally precisely adjust the longitudinal position of the upper cabin segment relative to the flexible connection device, so that the upper docking surface of the adjustment device is docked with the docking surface of the flexible connection device. The present invention can solve the problem that when a satellite micro-vibration test is conducted with a flexible connection device between cabin segments, when the upper and lower cabin segments are unloaded at the same time, the upper and lower cabin segments cannot be precisely docked using ordinary lifting equipment.
