Abstract

The invention discloses a six-degree-of-freedom microgravity test system with a double-layer structure, solves the problem of incomplete motion degree of freedom in an existing spacecraft ground test, and belongs to the field of spacecraft ground tests. The double-layer structure is adopted, an upper-layer structure is a complete five-degree-of-freedom simulator, a lower-layer structure is a displacement supporting platform, an air floating flat plate is arranged between the lower-layer structure and the upper-layer structure, position tracking of the upper-layer five-degree-of-freedom simulator can be achieved through active driving of Mecanum wheels, and the lower-layer structure further has a vertical zero-gravity compensation function. Through the structure, six-degree-of-freedom microgravity simulation of a spacecraft ground test system is achieved, and meanwhile the additional mass is reduced through the active tracking function of the lower layer structure. The six-degree-of-freedom microgravity test system is suitable for six-degree-of-freedom ground zero-gravity simulation tests of spacecrafts, and can meet high-precision dynamics and kinematics simulation test requirements.

Description

technical field [0001] The invention relates to a double-layer structure six-degree-of-freedom microgravity test system, which belongs to the field of spacecraft ground tests. Background technique [0002] The spacecraft needs to undergo sufficient ground tests before launch. High-precision distributed spacecraft need to analyze the coupling characteristics of attitude and orbit control. Complex space missions such as on-orbit capture and on-orbit docking need to evaluate the force of the mechanism during ground tests, so as to achieve better performance while on-orbit. running result. These complex space missions put forward high requirements for ground tests. Only high-fidelity ground tests can analyze the problems that may occur in the sky as clearly as possible on the ground and improve the reliability of on-orbit operations. The spacecraft operates in a microgravity environment on orbit, without external constraints, and is a free boundary condition, with 6 rigid body...
