The design of space debris removed simulation system based on flexible arm

Nowadays a great amount of space debris threat the safety of space activities, so the space debris removal becomes a hot research field. In particular, on the base of space mechanical arm technology, using mechanical arm to remove space debris proves feasible in the implementation. Traditional space mechanical arms are rigid arms, and in consideration of the uncontrolled momentum of rigid arm, this paper intend to use flexible arm to capture space debris, which can achieve the purpose of stably controlling collision momentum. According to the whole task process that flexible arm captures space debris, this paper built a model of flexible arm and space debris, and establishes their mathematics models. The simulation system is constructed based on the models, and use I/O Completion Port (IOCP) model to ensure the real-time transportation of data produced in collision. Finally, this paper designs a simulation application case to verify the ability of simulation system to support space missions.
