Abstract
This paper uses the Pro/Engineer to build a virtual prototype of the parallel robot.The ADAMS/View is also used to build the joints and motions for the virtual prototype and then the kinematics simulations run.Given the displacement and orientation of the moving platform,the changing curves of driving links can be obtained through measuring their lengths.Then the inverse kinematics problem is solved by using the ADAMS/Postprocessor to process the result of simulations.With this method,a lot of work can be avoided in programming and computation.And kinematics simulations of the parallel robot mechanism are realized with the CAE software on computer.An effective analysis method,which is used to rectify and control the physical model of the parallel robot mechanism,is obtained.
