Study on Synthesis of Hinged Four-Bar Linkage Straight-Line Mechanism Using Three Symmetric Points
Based on the fact that symmetric coupler curve can have three different tangent points with given straight-line, the three symmetric points of coupler locus was specified, and they was made into symmetric tangent points to determine the position of instant centre method. The size of the hinged four-bar linkage straight-line mechanism is determined using the position of instant centre method. The results were shown that coupler locus curve is obtained with this approach that is approximated with the intended straight-line precisely, and the basis of this approach is simpler than other analytic approaches.
