| Abstract: | A new kind of 3-DOF parallel mechanism 3-PCR was analyzed.Position equation of the mechanism was gotten by means of coordinate transformation.The velocity equation of the mechanism was gotten according to the derivation of the position equation,and then the inverse Jacobian matrix and the forward Jacobian matrix of the mechanism were gotten accordingly.Based on the Jacobian matrix,the singularity conditions and the singularity types of the mechanism were analyzed.Singularity analysis will lay the foundation... |
