Description

Technical field [0001] The invention relates to a dynamic physics simulation method, in particular to a full-state dynamics semi-physical simulation system of a space manipulator. Background technique [0002] The configuration of the space manipulator is very important for the space launch mission. A reasonable configuration design can not only reduce the space occupation of the manipulator during the launch process, reduce the system quality, reduce the launch cost, and more importantly, it can Reduce the disturbance of the star's attitude, reduce the requirements of the space manipulator for the support and locking mechanism, reduce the complexity of the entire system, and improve the reliability of the entire system. The space manipulator works in microgravity, and the ground simulation space microgravity environment cannot realize the full-state dynamics simulation of the complete work space of the manipulator. The dynamic model of the space manipulator under the microgravit...
