An Active Gravity Compensation System with Yaw Follow-up

Abstract

The invention provides an active gravity compensation system with a yaw follow-up function. According to the active gravity compensation system with the yaw follow-up function, the structure is simple, gravity compensation is thorough, and spacecraft space motion can be simulated. The active gravity compensation system comprises a horizontal follow-up supporting module, a rolling pitching low-friction follow-up module, a gravity compensation active follow-up module, a sensing measurement module and a coordination control module. The horizontal follow-up supporting module can actively follow longitudinal and transverse motion of a spacecraft, so that the gravity compensation active follow-up module is always in the vertical direction. The rolling pitching low-friction follow-up module can follow rolling motion and pitching motion of the spacecraft. The gravity compensation active follow-up module can completely compensate the gravity of the spacecraft and actively follow yaw motion of the spacecraft. The sensing measurement module can measure the change of the spacecraft in the vertical direction and the angle of the spacecraft horizontally rotating around the transverse direction. The coordination control module is responsible for collection and integration processing of system information, and thus all the modules of the system can work according to system design, so that the spacecraft space motion ground reappears.

Description

Technical field [0001] The invention belongs to the technical field of ground verification of spacecraft navigation, guidance and control systems, and in particular relates to a space environment simulation system for ground verification of spacecraft space motion. Background technique [0002] The degree of development of aerospace engineering determines whether it can seize the high-tech commanding heights and maximize the use of space resources. my country is actively carrying out aerospace technology research. In order to successfully complete space missions in extremely harsh space environments, sufficient experimental verification must be carried out on the ground. Reproducing the movement of the spacecraft in space on the ground can fully verify all aspects of the spacecraft in the space mission and ensure the smooth completion of the space mission. [0003] The most obvious feature of spacecraft movement in the space environment is the movement in the microgravity env...

Problems solved by technology

The suspension method can generally be divided into active gravity compensation and passive gravity compensation. The compensation accuracy of passive gravity compensation is low, which has a great impact on the test results; Provide three-degree-of-freedom motion space or multi-point suspension to provide six-degree-of-freedom motion space. In order to realize the goal of spacecraft motion reproduction, three-degree-of-freedom motion space is obviously not enough. Difficult control leads to poor test results, so it is necessary to find a system with simple structure, stable operation, complete gravity compensation and easy combination with horizontal motion platform to provide a nearly unconstrained microgravity motion environment for the spacecraft, and then reproduce its Real movement in space microgravity environment, to ensure the effectiveness of ground verification navigation, guidance and control systems
