Floating technique-based spacecraft 12-degrees-of-freedom full physical simulation device

Abstract

The invention discloses a floating technique-based spacecraft 12-degrees-of-freedom full physical simulation device and belongs to the technical field of a spacecraft motion simulation system. According to the technical scheme of the invention, the spacecraft 12-degrees-of-freedom full physical simulation device comprises a base, and two space simulators arranged on the base. Based on the gas floating technology, a gas floating platform and a two-dimensional gas floating turntable are adopted. In this way, the operating environment of a spacecraft under the effect of a micro disturbance torque in the outer space can be simulated. Based on the translational motion of the gas floating platform on the base in the free manner, a gas floating movement sliding table is enabled to slide back and forth along a gas floating guide rail, so that the translational motion of the spacecraft along the guide rail is simulated. The gas floating platform is capable of rotating in a direction vertical to the base, and the two-dimensional gas floating turntable is arranged on the gas floating movement sliding table. As a result, the attitude motion of the spacecraft can be simulated. the 12-degrees-of-freedom full physical simulation of the spacecraft can be realized. Meanwhile, the device is simple in structure, convenient to install and dismount, large in simulation motion range and high in accuracy.

Description

technical field [0001] The invention relates to the technical field of spacecraft motion simulation systems, in particular to a 12-degree-of-freedom full-physics simulation device for spacecraft based on suspension technology. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] The rendezvous and docking, hovering separation and other relative motion technologies of space vehicles are complicated. Due to the special environment, their reliability and accuracy need to be guaranteed, so they must be simulated on the ground. Although various countries have established their own space rendezvous and docking simulation systems since the 1960s, there are still few researches that can realize 12 degrees of freedom full-physics simulation.

Problems solved by technology

However, this method can only realize the simulation of attitude motion or rotational motion of the spacecraft in the environment of micro disturbance torque, and cannot realize the motion simulation of orbit or translation direction.

[0006] The existing technology is either a semi-physical simulation technology, which is a simulation based on dynamics and kinematics calculations, and cannot truly reflect the operating state of the spacecraft in space.

Either it can only realize the simulation of attitude motion or rotational motion of the spacecraft in the environment of micro disturbance torque, and cannot realize the motion simulation of orbit or translational direction
