A New Class of Six-Bar Mechanisms with Symmetrical Coupler Curves

Shieh, W-B.; Azarm, Shapour; Tsai, L-W.; Tits, A.L. (1996)

A new class of six-bar mechanisms with symmetrical coupler-point curves is presented. This class of mechanisms is made up of a four-bar linkage with an additional dyad to form an embedded regular or skew pantograph. Because ...

Multiobjective Optimization of a Leg Mechanism with Various Spring Configurations for Force Reduction

Shieh, W-B.; Azarm, Shapour; Tsai, L-W.; Tits, A.L. (1996)

In this paper, the design of a two degree-of-freedom leg mechanism is accomplished by a two-stage optimization process. In the first stage, leg dimensions are optimized with respect to three design objectives: minimize (i) ...
