Positional posture analysis of 3-DOF parallel mechanism

In this paper,a forward displacement solution of 3 degree of freedom(3-DOF) parallel mechanism is primarily discussed.The close loop equation is used for the positional posture analysis of the output piece of space 3-RPS parallel mechanism and the forward displacement of the mechanism is educed to acquire the positional posture of output piece.Finally,numerical emulation examples are performed for the positional posture analysis of the mechanism.
