The Dynamics Response Analysis on BKX-I Model PKM Based on FEM

Based on ANSYS,FEA models of a kind of 6-UPS parallel kinematic machine and its substructures were constructed,and PKM's transient dynamics response analysis was made.The displacement response curves of PKM along the suppositional axis of x,y and z were got respectively which the machine was under a certain transient load.On this basis,the disciplinarian of displacement transient dynamics response was analyzed and the characteristics and scalar of response were confirmed.
