The system has the characteristics of high precision and high frequency response, the system can improve the satellite ground simulation precision, and the realization of zero gravity in the vertical direction is a key technology related to the development of the six-degree-of-freedom satellite simulator. The invention belongs to the field of six-degree-of-freedom satellite simulators.

Description

technical field [0001] The invention relates to an air-floating pulley system, in particular to an air-floating pulley system for a six-degree-of-freedom simulator. The invention 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 the frontier direction of the aerospace field. As the technical basis for space on-orbit service and maintenance, it is also a 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, technical difficulties, and difficulties in conducting experiments in actual working environments. In recent years, the ground space environment simulation system developed based on the air-floating platform system has become the mainstream method for ground physical ...
