In response to the problem that the flexible robot in space arm is prone to vibration, the flexible hollow shell robot arm is covered with segmented constrained layer damping treatment, fully covered active constrained layer damping treatment, and fully covered passive constrained layer damping treatment respectively for better vibration suppressions. The dynamic simulation analysis of the three structural models is carried out by using finite element software, and the vibration suppression effect and damping characteristics of the three models are studied and compared. The segmentation method forms a cut in the constrained layer damping patch, which increases the shear deformation of the viscoelastic material in the vibration suppression process. Therefore the segmentation method can more effectively improve the damping characteristics of the structure compared with the other two structures. Moreover, it is found that the applicability of segmentation is related to the level of shear strain of the damping layer.
