Abstract

![CDATA[Geometric construction and analytical calculation are recognised as two basic approaches for planar mechanism design. However the geometric construction is only available for relatively simple cases while the analytical calculation is quite complicated and far from being visualised too. Both of them are complicated to be used for the Stephenson six-bar mechanism design due to complexity. Therefore the Computer-aided Design (CAD) geometric approach is developed to fulfil research needs. In this study, an approximate position and posture synthesis for the Stephenson six-bar mechanism is investigated via using the CAD geometric approach. Firstly using the geometric constraint and dimension driving techniques, a primary simulated mechanism is generated. Then based on different tasks of path and motion generations for the dimensional synthesis, the simulated mechanisms of the Stephenson six-bar mechanism are developed from primary simulation. The computer simulation results on approximation dimensional synthesis of the mechanism prove that the CAD geometric approach not only visualises the mechanism accurately and reliably but also increases the number of prescribed positions of synthesis for mechanism.]]
