The micro-gravity servo-balancing hanging and transferring device comprises a support frame body, a yaw servo unit, a balance hanging device, a longitudinal and lateral adjustment platform, a turntable, a load transfer mechanism and a simulated load unit, wherein the support frame body is fixedly connected with a foundation, and the yaw servo unit is rotatably connected with the support frame body, the longitudinal and lateral adjustment platform is installed on the bottom of the support frame body, the turntable is installed on the longitudinal and the lateral adjustment platform, the load transfer mechanism is installed on the turntable, the yaw servo unit is connected with the load transfer mechanism and the simulated load unit through the balance hanging device which is slidingly connected with the yaw servo unit. Real-time gravity balance and the passive servo movement in the process of stretching, contraction, position adjustment, rotation, retracting and unfolding of a load transferring mechanism are realized. The micro-gravity servo-balancing hanging and transferring device is a necessity for the development of the load transferring system under the microgravity environment.

Description

technical field [0001] The invention relates to a performance testing system of a mechanical component of a load transfer mechanism, in particular to a microgravity two-degree-of-freedom follow-up balance suspension and transfer device. Background technique [0002] At present, human activities to explore the vast universe are becoming more and more frequent, and various space missions are carried out, such as in-orbit docking of satellites and spacecraft, construction and maintenance of space stations, space robot activities, and extravehicular activities of astronauts, etc. In view of the high cost and special importance of these space missions, they must be required to have relatively high safety and reliability. Therefore, it is an indispensable research stage to carry out simulation tests of various aerospace equipment and personnel operation training on the ground in advance, so the ground micro (zero) gravity environment simulation technology has an indispensable posi...

Problems solved by technology

[0003] At present, there is no available multi-point balance hanging and transfer device for simulating the microgravity environment in China. When the simulated load unit is subjected to the six-dimensional force in the microgravity environment, it is difficult for the simulated load unit to form a real-time unmanned environment in the air.
