The invention belongs to the field of satellite simulators with six degrees of freedom.

Description

technical field [0001] The invention relates to an air flotation pulley system, in particular to an air flotation pulley system for a six-degree-of-freedom simulator, and belongs to the field of six-degree-of-freedom satellite simulators. Background technique [0002] With the development of aerospace technology, the on-orbit service and maintenance of space agencies has become a frontier direction in the aerospace field. As the technical basis for space on-orbit service and maintenance, it is also the current hot spot and difficulty in aerospace technology. However, space manipulation technology, as the technical basis for space agencies to complete application tasks, has difficulties such as complex systems, high technical difficulties, and difficulty in conducting experiments in the actual working environment. In recent years, the ground space environment simulation system developed based on the air flotation platform system has become the mainstream means of ground phys...
