Abstract

The invention provides a space six-degree-of-freedom rigid-flexible dynamics decoupling device. One end of a rotor of a first linear voice coil motor in the linear freedom degree direction is fixedly connected with a stator of a first rotating voice coil motor through a first flange plate; one end of a stator of the first linear voice coil motor in the linear freedom degree direction is fixedly connected with a rotor of a second rotating voice coil motor through a second flange plate; one end of a rotor of a second linear voice coil motor in the linear freedom degree direction is fixedly connected with a stator of the second rotating voice coil motor through a third flange plate; one end of a stator of the second linear voice coil motor in the linear freedom degree direction is fixedly connected with a rotor of a third rotating voice coil motor through a fourth flange plate; and one end of a rotor of a third linear voice coil motor in the linear freedom degree direction is fixedly connected with a stator of the third rotating voice coil motor through a fifth flange plate. The decoupling device provides six complete degrees of freedom, thereby completing the decoupling work of dynamics coupling between rigid and flexible parts on a spacecraft and improving the flexibility of the posture of the spacecraft and track control.

Description

technical field [0001] The invention relates to a rigid-flexible dynamic decoupling device with six degrees of freedom in space, and belongs to the technical field of dynamic decoupling devices. Background technique [0002] At present, the connection joints of rigid-flexible parts of spacecraft proposed at home and abroad are mainly direct fixed connection or three-degree-of-freedom connection. Among them, the three-degree-of-freedom connection can provide three rotational degrees of freedom. It has two disadvantages: one is that it still belongs to the fixed connection method in the three translational degrees of freedom, so the translational movement between the rigid-flexible parts of the spacecraft In terms of control, there is still a coupling phenomenon; the second is to use the way that the three axes intersect at one point, so during the three-dimensional rotation process, there will be certain mechanical interference, which affects the range of motion.
