The eight-bar scissor like linkages based on 2D linkages

An eight-bar scissor linkage mechanism based on a planar connecting rod was designed. The scheme design and research of the eight-bar scissor connecting rod mechanism were carried out, the motion analysis of the plane mechanism was carried out by using the complex vector method, the kinematic equation of the shear connecting rod mechanism was established, and the kinematic simulation analysis was carried out by Matlab software to obtain the angular displacement motion curves of each member. The results show that the designed eight-bar scissor linkage can meet the requirements of trajectory output, and there is no interference during the movement and the operation is stable, which lays a foundation for the optimal design.
