Abstract
Due to the manufacturing error or design tolerance, the joint in the traditional mechanism may contain clearance and hence resulting in poor position accuracy and/or wear problem of the mechanism. Thus, mechanisms using compliant joints may overcome such issues. This work investigates the advantages and disadvantages of various compliant joints. Then, a type of compliant joint made of open cross section and a combination of hollow and solid shafts is used in a five-bar mechanism. The position of the mechanism is analyzed and simulated via ANSYS software. Results of force input - displacement output by theoretical calculation and simulation are compared. Finally, an experiment on position input - displacement output is conducted to verify the precision and repeatability of the mechanism.
