Dynamic modeling and beating phenomenon analysis of space robots with continuum manipulators
文献摘要：
Space robotics has been used extensively in complex space missions.Rigid-manipulator space robots may suffer from rigid-body collisions with targets.This collision is likely to cause dam-age to the space robot and the target.To overcome such a problem,a novel Continuum-Manipulator Space Robot(CMSR)for performing on-orbit servicing missions is proposed in this paper.Compared with rigid-manipulator space robots,CMSRs are able to perform compliant oper-ations and avoid rigid-body collisions with a target.The CMSR consists of two kinds of flexible components,including solar arrays and continuum manipulators.The elastic vibrations of these flexible components disturb the position and attitude of CMSRs.The beating phenomenon intro-duced by the energy transfer among these flexible components can cause damage to solar arrays.The complicated dynamic coupling poses enormous challenges in dynamic modeling and vibration analysis.The dynamic model for CMSRs is derived and the mechanism of the beating phenomenon is analyzed in this paper.Simulation results show that an obvious beating phenomenon occurs and the amplitude of the solar arrays increases significantly when the natural frequencies of two kinds of flexible components are close.A method is provided to avoid the beating phenomenon.
