Abstract
The zero-gravity unloading method is a process method commonly used in the spacecraft field. It has been widely used in the docking installation and ground deployment test of load equipment such as solar wing and antenna, and it is used according to the situation of solar wing, antenna or other load equipment. Different gravity unloading tooling. This article analyzes and compares various unloading methods according to the installation requirements of a certain model of large parts in the zero-gravity state. On the basis of analysis, it is concluded that the traditional five methods of uninstallation are not suitable for the installation and uninstallation of large-scale equipment modules of this model. It is necessary to carry out targeted design according to the configuration characteristics, main structure characteristics and installation requirements of large-scale equipment to realize large-scale modules. Stress-free assembly in zero-gravity state. As a result, a method for installing large parts of spacecraft based on zero-gravity unloading was proposed, which formed a large-scale component docking technology and realized the smooth assembly of the product.
