Abstract

The invention discloses a method for three-dimensional dynamic simulation in the space manipulator auxiliary butt-joint process and relates to a method for three-dimensional dynamic simulation. The method is used for solving the problem that due to the fact that command and control personnel on the ground and an astronaut cannot visually see a manipulator, great trouble is brought for control over movement of the manipulator. The method comprises the specific steps of realization environment establishment, space manipulator three-dimensional virtual modeling and displaying, movement model establishment, manipulator movement simulation based on a rocking bar controller, real-time rendering of force-receiving and deformation of a manipulator flexible arm lever, dynamic display of a movement track of the tail end of the manipulator, multi-view interactive roaming in the auxiliary butt-joint process and project value and curve display in the space manipulator auxiliary butt-joint process. The method is applied to the technical field of computer analogue simulation.
