| Abstract: | In order to investigate kinematic performance of a novel planar 2-DoFs translation parallel manipulator.The kinematic model is established and analytical forward and inverse solutions are obtained.Indices of kinematic performance is defined,the expressions of indices of kinematic performance with different architectures are analyzed.The relationship between performance indices and the geometric parameters of mechanism was probed,the corresponding performance atlas has been plotted,the advantage of larger workspace/volume ratio and smaller guide length of this Paralle Manipulator is obtained,these atlas are an important base of reference for the optimal design of this parallel manipulator. |
