Numerical simulation of posture in 3-DOF parallel mechanism based on VB

摘要

In this paper, a forward displacement solution of 3 degree of freedom (3-DOF) parallel mechanism is primarily resolved. The close loop equation is adopted for the positional posture analysis of the output displacement of spatial 3-RPS parallel mechanism, the forward displacement of the mechanism is educed, and the positional posture of output displacement is acquired. Finally, numerical examples are performed for the positional posture analysis of the mechanism.
